Ratio which number goes first

Writing the ratio using a colon, we get 6 : Note that this can be reduced, like a fraction, by dividing both numbers by a common factor -- in this case, 3.

In simplest form, the ratio is 2 : 7. The ratio of apricot juice to the total amount of punch is 21 : But this ratio is probably more clearly written as a fraction, since the apricot juice makes up a fraction of the whole. To reduce the fraction, divide both the numerator and the denominator by 3. An adult scolopendromorph centipede has 46 legs and 8 eyes. In a group of centipedes of the same species, what is the ratio of legs to eyes? Note that it doesn't matter if there are or 10, centipedes; the ratio of legs to eyes will remain the same.

Writing the ratio using a colon, we get 46 : 8. Divide both numbers by 2. In simplest form, the ratio of legs to eyes is 23 : 4. The ratio of the number of apples to all the pieces of fruit can be expressed by the ratio If you change the order of the numbers in a ratio you also change the meaning of the ratio, so the order of the numbers matters.

This means is not equivalent to There are two basic types of ratio relationships. Using the fruit example, if the bag held 4 apples and 2 bananas, then the ratio between apples and bananas can be expressed as Notice that the total number of pieces of fruit does not enter into the part-to-part ratio.

Any ratio can be written as a fraction. The ratio should be simplified either before or after converting to ensure the fraction is in lowest terms. You can also convert a fraction to a ratio by reversing the above operation.

A number that is expressed as a percentage can be seen as a type of ratio since the number to the left of the percent sign is being compared to In this case 0. This would be read as " the smaller bar is 0.

A ratio is how many times bigger one thing is than another. It's a number you multiply by to get one thing from another. But remember , when you find the ratio of two quantities, they must be in the same units. If you know that John and Jim have weights in the ratio 1.
