Answer:
the answer is C
Step-by-step explanation:
So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4? let's see.

you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4 and stop there.
then you'll notice that 12/24 is really 2/4 in disguise.
Answer:
x = 27
Step-by-step explanation:
Given
- 6 = 2 ( add 6 to both sides )
= 8 ( square both sides )
2x + 10 = 8² = 64 ( subtract 10 from both sides )
2x = 54 ( divide both sides by 2 )
x = 27
4 1/3 x 3 x 1 ¼
12 ¾ x 3 x 1 1/4
Your lucky that I just had the question on a test and realized you didn't make it into fractions.
