Answer 3

To multiply a fraction by a whole number, you can simply multiply the whole number by the numerator of the fraction and keep the denominator the same. Then, simplify the resulting fraction if possible.

Let's solve the expression:

7/12 * 1 5/7

First, convert the whole number to an improper fraction:

1 = 7/7

Now the expression becomes:

7/12 * 7/7 * 5/7

Now, multiply the fractions:

(7 * 7 * 5) / (12 * 7)

35 / 84

The result, after simplifying the fraction, is 35/84.
