Answer 3

Sure, I can help you with these mathematical expressions. Let's solve each one step by step:

1. $0.4a \times 1.9b$

To solve this, we'll multiply the coefficients and the variables separately:

$0.4 \times 1.9 = 0.76$

So, the expression becomes $0.76ab$.

2. $0.27a \times 0.36$

Similarly, we'll multiply the coefficients:

$0.27 \times 0.36 = 0.0972$

So, the expression becomes $0.0972a$.

3. $0.4a \times 8b \times 0.3c$

Multiply the coefficients and the variables:

$0.4 \times 8 \times 0.3 = 0.96$

So, the expression becomes $0.96abc$.

4. $1.2x \times 0.3 \times 5z$

Multiply the coefficients and the variables:

$1.2 \times 0.3 \times 5 = 0.18$

So, the expression becomes $0.18xz$.
