To determine what percent 1.5 is of 20, we can use the formula for finding the percentage:
Percentage = (Part / Whole) * 100
In this case, the part is 1.5, and the whole is 20. Plugging in the values:
Percentage = (1.5 / 20) * 100
Calculating this gives us:
Percentage = 0.075 * 100 = 7.5%
So, 1.5 is 7.5% of 20.
