Answer :

Using proportions, he should put 3 yellow blocks on each tower.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The proportion between the number of yellow blocks and the number of red blocks is given by:

21/7 = 3.

Since each tower will have one red block, considering the proportion, he should put 3 yellow blocks on each tower.
