Answer 1

It is true that the ratio 4/7 to 8/9 has a unit rate of 9/14.

In a unit rate, the denominator becomes 1. So we divide the numerator by the denominator to make it one.

Now according to the question we have been given two ratios which are 4/7 and 8/9.

We have to find the unit rate of 4/7 to 8/9. For this we will divide 4/7 by 8/9. We will get,’

                            =  (4/7)/(8/9)

It can be written in a simpler way as

                           = (4*9)/(7*8)

                           = 36/56

Reducing it into a simple fraction we get,

                           = 9/14

Thus, the ratio 4/7 to 8/9 has a unit rate of 9/14. Hence the statement is true.
