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
