Question

Compare the ratios 4:5 and 16:20.

Answer 1

They are equal

Explanation:

When comparing ratios, we simply want to find out if the numbers are greater than, less than, or equal to each other. We have 4:5 and 16:20.

To find out the comparison;

Step 1: We find the LCM of the denominators ie 5 and 20, which is 20

Step 2: We divide the LCM by both sides, like this: 20÷5=4 and 20÷20=1.

Step 3: Now, multiply each ratio by the result of its individual denominator division ie

`(4 * 4)/(5 * 4) \: and \: (16 * 1)/(20 * 1) = (16)/(20) \: and \: (16)/(20)`

Step 4: Convert back to ratio form, we have: 16:20 and 16:20

From the above ratios, we have found out that 4:5 and 16:20 are equal when compared.

I hope this helps.
