The correct options are
A 24
B 8 times as many as 3
D 2 times as many as 12
3 times as many as 8 = 3 x 8 = 24
8 times as many as 3 = 8 x 3 = 3 x 8
= 24
2 times as many as 12 = 2 x 12
To find 2 x 12, split 12 as 12 = 10 + 2.
Multiply 2 by 10 and 2 and find the sum.
2 x 10 = 20
2 x 2 = 4
∴ 2 x 12 = 24
Thus, the correct answers are 24, 8 times as many as 3 and 2 times as many as 12.
