Find the number that is exactly halfway between 3/10 and 4/5

In order to answer you ned to find a common denominator.

Since 5 is a multiple that goes into 10 that can be your common denominator

This means its 3/10 and 8/10

The number exactly halfway would be 5.5/10

If you need a whole number as your numerator it could also be 11/20

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
