Solution - Long multiplication
0.2
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | ones | . | tenths |
| 0 | . | 1 | |
| × | 2 | ||
Ignore the decimal points and multiply as if these are whole numbers (as if each most right digit is the ones digit):
In this case we removed 1 decimal place(s). So once calculated, the result will be reduced by the factor of 10.
| Place value | ones |
| 1 | |
| × | 2 |
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (2) of the multiplier 2 by each digit of the multiplicand 1, from right to left.
Multiply the ones digit (2) of the multiplicator by the number in the ones place value:
2×1=2
Write 2 in the ones place.
| Place value | ones |
| 1 | |
| × | 2 |
| 2 |
Because we have 1 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 1 time(s) to the left (reducing the result by the factor of 10) to get the final result:
The solution is: 0.2
