The concepts for this exercise are summarized below.
For a complete discussion, read the text.
Multiplying fractions is easy:
just multiply the numerators, and multiply the denominators.
(Some people refer to this as multiplying across.)
That is,
AB
⋅C
D=ACBD
Every division problem is a multiplication problem in disguise:
to divide by a number means to multiply by its reciprocal.
That is, x divided by y
is the same as x times the reciprocal of y .
In symbols,
x÷y=xy
=x⋅1
y
Here's what it looks like with fractions:
AB
÷C
D=A
B⋅
DC
EXAMPLES:
13
⋅2
5=2
15
16
⋅3
7=3
42=
114
(You may input your answer in either form, simplified or not.)
13
÷2
5=1
3⋅
52=
56
You must input your answer as a diagonal fraction (like "2/5"), since you can't input horizontal fractions.
