Step 3 :. Make the denominators of both the fractions same as the value of least common multiple found in step 1 using multiplication. Step 4 :. After getting same denominator for both the fractions, compare the numerators and decide which fraction is greater. The fraction which has larger numerator is greater in value. Example 1 :. Solution :. Write the given ratios as fractions.
Compare the numerators. So, 5 : 7 is greater than 3 : 7. Example 2 :. The least common multiple of the denominators 5 and 7 is Make the denominators of the fractions as 35 using multiplication.
So, 3 : 5 is greater than 4 : 7. Example 3 :. Compare 5 : 12 and 7 : The least common multiple of the denominators 12 and 18 is Make the denominators of the fractions as 36 using multiplication. So, 5 : 12 is less than 7 : Example 4 :.
The least common multiple of the denominators 10 and 4 is Make the denominators of the fractions as 20 using multiplication. Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.

But you should be as explicit as you can. It is better to say John's weight is 1. When the ratio is expressed as a fraction, the convention is that the first mentioned item is on top numerator. Home Contact About Subject Index. The relationship between two measures, expressed as the number of times one is bigger or smaller than the other. For example, the ratio , in terms of shots made and shots taken, means that three out of every five shots goes in. When you have multiple ratios, you may want to determine whether they are equal or if one of them is larger.
To compare ratios , you need to have a common second number. By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are and , multiply 3 by 15 and 5 by 15 to get Multiply both numbers in the second ratio by the original second number of the first ratio.
In this example, multiply 9 by 5 and 15 by 5 to get Compare the results.
