Examples:3/8 / 3/4.3/8 * 4/3=12/24

a.8/9 / 2/3=x

b.72/100 / 2/5=x

c.9/20 / 3/4=x

d.40/50 / 4/5=x

How to multiply fractions

a.4/5 * 7/8=x

b.5/9 * 3/5=x

c.2/8 * 6/20=x

Multiplying/Dividing fractions and improper fractions

Sometimes in a problem,you might find a problem like this 5/6 * 6 and 1/2 or 7 and 3/4 / 2/3.You can't divide or multiply improper fractions,so you need to change it to a fraction.So like 6 and 1/2 can be 13/2, so multiply it by the other fraction which is 5/6 * 13/2=65/12.

Examples:5/7 * 4 and 6/10,5/7 * 46/10=230/70

a.4 and 2/3 / 1/2=x
