Question

If 1 dollar equals 0.72p what is the exchange rate from pounds to dollars

Answer 1

The question is asking for what 1 pound is in dollars based on the ratio.

0.72p is equal to 72/100 pounds.
On the left is dollars and the right is the pounds
1 = 72/100

Multiply both sides by 100 as we want the right side to equal 1
100 = 72

Divide both sides by 72 to get 1 (pound) on the right

100/72 = 1

This means that the answer is:
1 pound is equal 100/72 or 1.38888888…. Dollars
