Question

What does it mean to multiply and divide fractions

Answer 1

Answer:

Step-by-step explanation:

o multiply fractions, all you have to do is multiply the numerators and denominators and simplify the result. To divide fractions, you simply have to flip the numerator and denominator of one of the fractions, multiply the result by the other fraction, and simplify.

Answer 2

As you have not asked for any particular question so I am writing some examples to make you understand your question.

Example 1

1/5 X 3 = 3/5

Example 2

9X 2/3=6. here 9 and 3 both can be simplified by 3 tables to left with 3x2= 6

Example 3.

3 3/4 X 3/4X1 7/9

in this case where some numbers are given as a mixed number so we first change all mixed numbers into top-heavy fractions also called improper fractions.

= 15/4X 3/4 X16/9

=5.

Here we simplify the numerator and denominator numbers by the same number.

Now for division

Example 1

2/5 divided by 3

the division sign is changed to a Multiplication sign and the number after the division sign will be upside down ie numerator will become denominator and denominator will become numerator

= 2/5X 1/3 as here none of the numbers can be reduce to a simpler form we simply take the product of numerator and denominator

= 2/15 Answer

Example 2.

3 1/2 divided by 3/4

= 7/2 divided by 3/4

= 7/2X 4/3

= 14/3= 4 2/3 mixed number answer

Example 3.

42/15X16/21 division sign 48/20 in this question first step to change division sign to multiplication sign and the fraction after division only that will be upside down

so the question becomes

=42/15 X 16X 21 X 20/48

=2/3 Ans
