Question

Bob's Gift Shop sold 450 cards for Mother's Day. One salesman, Ximena, sold 4% of the cards sold for Mother's Day. How many cards did Ximena sell?

Answer 1

18

Explanation:

since the gift shop sold 450 cards mother's Day.

and the salesman only sold 4% of cards on the same day. all I have to do is fine 4% of 450 because he only sold 4% out of 450 cards on mother's Day.

explanation 1:

a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. I'll divide 4 by 100 since that is the percentage of cards he sold in times 450 to find how many he sold.

`4 / 100 * 450 = 18`

explanation 2:

to converge a percentage into a decimal you have to divide by 100. 4 / 100 is 0.04 you could also move the decimal point to units till left those are two ways to convert a percentage into a decimal. now multiply

450 × 0.04 which equals 18

example:

first step

`4 / 100 = 0.04`

second step

`450 * 0.04 = 18`

answer

the salesman sold 18 cards out of 450.
