Question

What is 5 1/4 times 3 3/4

Answer 1

19 11/16

Explanation:

Convert to decimal form.

5 1/4 = 5.25

3 3/4 = 3.75

Multiply

5.25 x 3.75 = 19.6875

(If you are working out the problem on paper notice how the answer has 4 decimal places. This is because each factor has 2 decimal places so the final answer would have a total of 4.)

Convert back to a fraction

Take the 0.6875 and put it over it's place value which is the ten thousandths place.

`(6875)/(10000)`

Simplify

Find the GCF and divide it into both the numerator and the denominator.

`(6875/ 625)/(10000/625)` =
`(11)/(16)`

The original answer was 19.6875 so we also have to put 19 back into the answer.

So the answer is
`19(11)/(16)`
