Answer 2

To solve this expression, follow these steps:

1. Multiply the fractions separately.
2. Add the results of the two multiplications.

Let's go through it step by step:

First, multiply the fractions:

• $\frac{21}{44} \times \frac{11}{16}$
• $\frac{21}{44} \times \frac{5}{16}$

Step 1: $\frac{21}{44} \times \frac{11}{16} = \frac{231}{704}$

Step 2: $\frac{21}{44} \times \frac{5}{16} = \frac{105}{704}$

Now, add the results of the two multiplications: $\frac{231}{704} + \frac{105}{704} = \frac{336}{704}$

Simplify the fraction: $\frac{336}{704} = \frac{12}{25}$

So, $\frac{21}{44} \times \frac{11}{16} + \frac{21}{44} \times \frac{5}{16} = \frac{12}{25}$
