of means multiply. I don't think the meaning ever changes when you are using fractions.
So to get the answer
4/7 * 5/6 Multiply numerator by the numerator and denominator by denominator of each fraction
numerator: 4 * 5 = 20
denominator: 7 * 6 = 42
numerator of answer / denominator of answer = 20 / 42 This will reduce. Divide each part by 2
20 / 2 = 10
42 / 2 = 21
10 / 21
Answer 10 / 21
