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

Sagot :

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
