Answer 2

Let's solve the given expressions step by step:

1. $8.9 \times 3.7 + 6.3 \times 8.9$

   $$\begin{align*} &= 33.03 + 56.07 \\ &= 89.1 \end{align*}$$

2. $0.2 \times 9.3 + 7.8 \times 0.2$

   $$\begin{align*} &= 1.86 + 1.56 \\ &= 3.42 \end{align*}$$

Therefore:

• $8.9 \times 3.7 + 6.3 \times 8.9 = 89.1$
• $0.2 \times 9.3 + 7.8 \times 0.2 = 3.42$
