Multiply 7 3/5 x 6.

9.

Division

a.

instance, dividing the numerator of a fraction reduces the number of

fractional units, but the size of each unit remains the same. Multiplying

the denominator reduces the size of the fractional units, but the number of

fractional units remain the same. This is the same as inverting the divisor

and multiplying. Thus, 7/8 ƒ 3/4 and 7/8 x 4/3 give the same answer. The

fraction turned upside down is called the reciprocal.

b.

denominator. Invert this fractional form. Then multiply.

EXAMPLE

Divide 7/11 by 3. Since 3 = 3/1, the reciprocal of 3 is then 1/3.

7/11 ƒ 3

= 7/11 x 1/3 = 7/33.

c.

Invert the fraction and multiply.

EXAMPLE

Divide 13 by 3/7.

Invert 3/7 to 7/3, then multiply.

13 ƒ 3/7 = 13 X 7/3 =

91/3 = 30 1/3.

d.

Invert the divisor, that is the second fraction, and multiply.
