1/2 of 12 = 1/4 of ?

1/3 of 90 = 2/3 of?

1/2 of 12 = 1/4 of 24 and 1/3 of 90 = 2/3 of 45

Step-by-step explanation:

1. 1/4 of 24

half of 12 is 6.

6+6+6+6 = 24

1/4 of 24 is 6

1/2 of 12 is 6

2. 2/3 of 45

1/3 of 90 is 30

15+15+15 = 45

so 2/3 would be 30

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
