Farid takes 7/8 teaspoon of allergy medicine every day. How much medicine will he take in one week?

He takes 7/8 per day and there are 7 days in a week

so multiply 7/8 by 7/1 since 7 divided by 1 is still 7.

(7/8) x (7/1)

then multiply the top numbers for numerator and bottom for denominator

7 x 7 49

you get

8 x 1 8

if you need to go further you divide the 49 by 8 and get 6.125.

6.125 = 6 and 1/8

6 is the whole number and. 125 out of 100 equals 8
