Here are the solutions for the multiplication problems.
Step-by-step Calculation:
1.
$0.9 \times 0.7$: Multiply $9 \times 7 = 63$. There is 1 decimal place in the first number and 1 in the second, so the answer needs 2 decimal places.
Result:
0.63
2.
$0.4 \times 0.03$: Multiply $4 \times 3 = 12$. There is 1 decimal place plus 2 decimal places, so the answer needs 3 decimal places. Add a zero to the front.
Result:
0.012
3.
$0.2 \times 0.5$: Multiply $2 \times 5 = 10$. The answer needs 2 decimal places ($0.10$), which simplifies to $0.1$.
Result:
0.1
4.
$0.5 \times 0.6$: Multiply $5 \times 6 = 30$. The answer needs 2 decimal places ($0.30$), which simplifies to $0.3$.
Result:
0.3
5.
$1.0 \times 0.05$: Multiply $1 \times 5 = 5$. The answer needs 2 decimal places.
Result:
0.05
6.
$0.7 \times 0.8$: Multiply $7 \times 8 = 56$. The answer needs 2 decimal places.
Result:
0.56
7.
$0.5 \times 0.5$: Multiply $5 \times 5 = 25$. The answer needs 2 decimal places.
Result:
0.25
8.
$0.7 \times 0.03$: Multiply $7 \times 3 = 21$. The answer needs 3 decimal places ($1 + 2$). Add a zero to the front.
Result:
0.021
9.
$0.3 \times 0.07$: Multiply $3 \times 7 = 21$. The answer needs 3 decimal places ($1 + 2$). Add a zero to the front.
Result:
0.021
10.
$0.2 \times 0.06$: Multiply $2 \times 6 = 12$. The answer needs 3 decimal places ($1 + 2$). Add a zero to the front.
Result:
0.012
11.
$0.6 \times 0.08$: Multiply $6 \times 8 = 48$. The answer needs 3 decimal places ($1 + 2$). Add a zero to the front.
Result:
0.048
12.
$0.8 \times 0.1$: Multiply $8 \times 1 = 8$. The answer needs 2 decimal places. Add a zero after the decimal point.
Result:
0.08
13.
$0.2 \times 0.10$: Multiply $2 \times 10 = 20$. The answer needs 3 decimal places total ($1 + 2$), which is $0.020$, or simply $0.02$.
Result:
0.02
14.
$0.4 \times 0.2$: Multiply $4 \times 2 = 8$. The answer needs 2 decimal places. Add a zero after the decimal point.
Result:
0.08
15.
$0.7 \times 0.2$: Multiply $7 \times 2 = 14$. The answer needs 2 decimal places.
Result:
0.14
16.
$0.6 \times 0.7$: Multiply $6 \times 7 = 42$. The answer needs 2 decimal places.
Result:
0.42
