Math CentralQuandaries & Queries


Question from Kenneth:

Should ratios contain only whole numbers and not any fractional numbers?

For example, 8:1, 2:5 have whole numbers. The ratios 2.5:10 and 1:4.5 do not have just whole numbers entirely.

If it is incorrect to express a ratio with fractional numbers, why are complex fractions correct?

I thank you for your reply.

Hi Kenneth,

Ratios should be expressed using whole numbers if possible. For your example 2.5:10 I would multiply each side by 10 to get 25:100 and then multiply each side by 1/25 to get 1:4.
