Answer 2

Let's solve the expressions step by step:

1. $6 \times \frac{2}{11} \times 5 \times \frac{1}{8} + 1 \times \frac{9}{11} \times 5 \times \frac{1}{8}$

First, perform the multiplications and divisions within each set of parentheses:

$6 \times \frac{2}{11} \times 5 \times \frac{1}{8} = \frac{60}{88} = \frac{15}{22}$ $1 \times \frac{9}{11} \times 5 \times \frac{1}{8} = \frac{45}{88}$

Now add the two results:

$\frac{15}{22} + \frac{45}{88} = \frac{330 + 45}{22 \times 8} = \frac{375}{176}$

2. $6.71 \times 2.8 - 4.71 \times 2.8$

Perform the multiplications:

$6.71 \times 2.8 = 18.808$ $4.71 \times 2.8 = 13.188$

Now subtract the second result from the first:

$18.808 - 13.188 = 5.62$

So, the solutions are:

1. $\frac{375}{176}$
2. $5.62$
