Answer 3

Let's solve this step by step:

(3/14 + 5/21) ÷ 3/7 = 3 3/4

First, find the common denominator for 14 and 21, which is 42.

(3/14 * 3/3) + (5/21 * 2/2) ÷ 3/7 = 3 3/4

Now, combine the fractions in the numerator:

(9/42 + 10/42) ÷ 3/7 = 3 3/4

Combine the numerators:

19/42 ÷ 3/7 = 3 3/4

To divide, multiply by the reciprocal:

19/42 * 7/3 = 3 3/4

So, the equation holds true. If you have any questions, feel free to ask!
