Dividing Fraction

6 / 1/2=
you can turn it into 6/1  /  /1/2
how many groups of 1/2 will go into 6?

by multiplying the 1/2 by 6/1 it will equal to 12

why did i multiply it?
because I reciprocal the 1/2 and get 2/1

so 2/1 x 6/1 = 12

here's another question

7 / 1/2

by turning the 2nd number into a reciprocal i would get 2/1

7/1 /  1/2=     7/1 x 2/1= 14

as you can see if you divide the 6 into a 1/2 will equal you 12 parts

by using reciprocal i would multiply instead of drawing , dividing and counting

math test corrections





1)  2 1/2 x 1 3/5

corrections:

3/2 x 8/5 = 40/ 10 simplify 4

2) 2 1/4 x 1 1/3

corrections:

improper the mixed and get:
9/4 x 4/3= 36/12 = 3

3) Tamar had an apple pie in her refrigerator  she ate 1/4 of this piece of pie. what fraction of a whole pie did she eat?

corrections
1/2 x 1/4 = 1/8

4) in computer terminology, a bit is 1/8 of a byte. how many bits equal 16 bytes?

corrections:
1/8    /  16/1
1/8  x  1/16 = 1/128
