Answer:

80

Step-by-step explanation:

When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.

We can change 90% into a decimal, and put in x, which is what our answer will be!

0.9*x=72

We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have

x=72*10/9, which is 80.
