Is #4 5/8 " plus "3 2/5# greater than #1 5/8 " plus " 2/5#?

Answer 1

The sum of the first two fractions will be greater than the sum of the last two fractions.

It is not necessary to find the two answers to be able to tell instantly that the first sum will be much more than the second.

This can be seen by looking at the whole numbers.

In the first sum, the whole numbers are #4 and 3# which will give a sum of 7.

In the second sum, the whole numbers are #1 and 0#, which have a sum of only 1.

As all the fraction parts are proper fractions, they will not make much difference.
