Answer:
B
Step-by-step explanation:
We know that all of the ages are 7 apart so we don't need to mess with that.
Since Ed's age is 3/2 times Ted's age, we can make an equation.
Ted = t
Ed = e
e = 3/2t
Now we can just substitute and see if it checks out.
21 = 1.5 * 14
And since they are equal B is the answer.
1/8 Divided by 4 =
2/8 + 3/9
