Question

Which statement and reasoning is true for finding the common denominator for the fraction 1/4 and 1/8?

Answer 1

Answer:

A I can use 8 because 4*2 =8

C I can use 16 because 4*4 = 16 and 2*16 = 16

D I can use 24 because 6*4 =24 and 3*8 =24

Step-by-step explanation:

1/4  and 1/8

The multiples of 4

4,8,12,16,20,24

The multiples of 8

8,16,24,32

The first multiple that 4 and 8 have in common is 8  so that is the least common denominator

But 16 and 24  are also multiples  so they are also common denominators of 4 and 8.  ( They are not the least common multiple)
