Question

Elise and her younger brother, Reid, take turns loading the dishwasher after dinner. Because she is older, Elise loads the dishwasher 4 times for every 3 times Reid loads it. If Elise and Reid have loaded the dishwasher 84 times in all this year, how many times has Elise loaded the dishwasher?

Answer 1

48

Explanation:

so for every 3 Reid washes there are 4 Elsie washes

the ratio of washing is 3:4

lets add 3 and 4 up

3 + 4 = 7

now lets divide the total number of washes by the added ratio

84/ 7

=12

now we know that 1 part is 12

to find Elsie's part we need to x 12 by how many parts she has got

she washed 4 times

4 x 12

=48
