What is the difference between 100/30 and 10/3

The mystery of the betting ring, after all, is also the fellowship of the ring. But Racing For Change is acutely conscious that the sport has an ageing audience, and is prepared to take risks in order to tempt the holy grail of to year-olds.

Tic-tac men themselves have been rendered largely redundant by changes in the betting ring. The market is increasingly focused on Betfair, and those bookmakers who do need to communicate significant business can rely on earphones and radios. There would have been dozens of tic-tac men in the ring at Cheltenham or Royal Ascot only a few years ago; now there might only be a couple. We need to overhaul betting language that is alien to anybody who went to school since the UK went decimal in The reformers can argue not only that decimal odds are more accessible than, say, or , but also that the established betting market is increasingly conversant in decimal odds.

The biggest single change in the modern wagering landscape, since the legalisation of betting shops in , has been the arrival of Betfair. During the past decade, the pioneering betting exchange has gone from nowhere to generating huge pools on horseracing and other sports.

Almost every serious punter will now be familiar with a betting exchange — where every transaction is decimal. The big bookmaking chains, acknowledging this, already give their online clients the option of decimal odds. The betting ring is notoriously conservative, and only recently replaced blackboards with digital displays. Between and , traditional starting prices will tend to be returned only in fractions of , or Decimal returns would express these as 2.

McCririck predicts that bookmakers will slow down any easing in the odds as a result. It has been brought in as a PR exercise, to bring in younger people, and quite rightly so.

Note: for a lesson, a teacher will need elastics tape measures of various lengths, because the elastic can only be stretched - it cannot be shrunk. This elastic tape measure model was developed by J. The ratio of 1 : 3 tells us the ratio of shaded : unshaded.

The ratio of 3 : 1 tells us the ratio of unshaded : shaded. The ratio of 1 : 4 tells us the ratio of shaded : whole. A ratio is another way of comparing quantities. Each quantity must be measured in the same units.

An advantage of ratios is that we can compare several things at once. Although ratios must have each quantity measured in the same units, the units are not fixed. This fact makes ratios very versatile to use in everyday situations.

The order in which a ratio is written is very important. If we say the ratio of the number of girls to the number of boys is this is very different to saying the ratio of the number of girls to the number of boys is A ratio can be written in different ways;.

Example 4: Let's say I want to make the paint colour 'sky blue' and I know that the way to do this is to mix 1 part blue with 4 parts white. This means there is a ratio of blue to white of In this case 1 litre of blue to 4 litres of white, making 5 litres of sky blue paint.

To make double the quantity of paint I can mix the blue to white as a ratio of This will make the same colour. The ratios of and are equivalent, and worked out in the same way as equivalent fractions. We multiply each part of the original ratio by the same number and we can find equivalent ratios. Sharing quantities in a given ratio. The ratio of 2 : 2 : 1 means that the inheritance is divided into 5 portions - two people each receive 2 portions and one person receives 1 portion.

Relationships - decimal fractions, common fractions, percent and ratio. We can use examples to illustrate the relationships between decimal fractions, common fractions, percent and ratio. Example 7: Ratios and fractional parts. A litre of mixed cordial requires mls of cordial and mls of water. How can we represent this as a ratio and a fraction? The ratio of cordial to water is : or 1 : 3. One part cordial to 3 parts water. We talk about the ratio of cordial to water in many different ways: For every cup of cordial there are 3 cups of water.

There is 3 times as much water as cordial. Can you think of any more ways? Example 8: Ratios and fractional parts. A group of people is made up of 60 males and 40 females. The ratio of males to females is 60 : 40 or 6 : 4. This means that overall there is a higher proportion of males in the group, and for every 6 males there are 4 females.

So we can also say that 6 out of every 10 people are males and 4 out of every 10 people are females. The 3 ratios that represent the relationships of males and females in this group of people are:.

Which ratio we choose depends on we want to say. The number of males to the number of females is 6 : 4. The number of males to the number of people is 6 : The number of females to the number of people is 4 : In the early stages of introducing ratio at a primary level we generally discuss ratios in terms of a part to part or, quantity to quantity, comparison.

At this stage part to whole relationships are often better represented by fractions or percents with which students already have some experience. When part to whole ratios are introduced care must be taken to ensure students clearly understand what is being represented. You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:.

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!
