Answer 2

1. To multiply fractions, we multiply the numerators (top numbers) together and the denominators (bottom numbers) together. So for the first problem:

(10/11) × (1 11/21)

First, we need to convert the mixed number (1 11/21) to an improper fraction. To do that, we multiply the whole number (1) by the denominator (21) and add the numerator (11):

1 × 21 + 11 = 21 + 11 = 32

So the mixed number becomes 32/21.

Now we can multiply the fractions:

(10/11) × (32/21)

Multiplying the numerators and denominators:

(10 × 32) / (11 × 21) = 320 / 231

This fraction can be simplified by finding the greatest common divisor (GCD) of the numerator and denominator, which is 7:

320 ÷ 7 = 45 5/7 231 ÷ 7 = 33

So the simplified fraction is:

45 5/7 / 33

2. For the second problem:

(7/16) × (2 2/7)

Convert the mixed number to an improper fraction:

2 × 7 + 2 = 14 + 2 = 16

So the mixed number becomes 16/7.

Multiply the fractions:

(7/16) × (16/7) = (7 × 16) / (16 × 7) = 112 / 112

This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 112:

112 ÷ 112 = 1

So the simplified fraction is:
