A woman saves 38.25 Egyptian pounds of her salary every month. How much has she saved from her salary in 100 months?

To answer this question, we need to perform a multiplication. The total amount saved is equal to the amount saved each month multiplied by the number of months. These values are given in the question. The amount saved each month is 38.25 Egyptian pounds, and the number of months is 100.

So our calculation is 38.25 multiplied by 100. We’re multiplying a decimal number by 100. When multiplying a decimal number by 100, the decimal point moves two places to the right. The decimal point would now appear at the end of this number. But as there no digits after the decimal point, we don’t actually need it.

The total amount that the woman has saved in 100 months is 3825 Egyptian pounds.
