I'm having trouble understanding equivalent fractions. I'm getting frustated with myself, I feel so stupid for not understanding it.

Here's the 2 questions I have to answer:

1. Find a number for x in 18/27 = x/3 so that the fractions are equivalent.

2. Find a fraction equivalent to 3/8.
a. 15/40
b. 3/4
c. 6/24
d. 12/16

    1. 18/27 = x/3
    27x = 54
    x = 54/27 = 2

    2. Reduce fractions a, c and d to loweest terms to find which equals 3/8. The answer is not b, since 3/4 is not equal to 3/8
