Solution - Long multiplication
0.00000007
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | ones | . | tenths | hundredths | thousandths | ten thousandths | hundred thousandths | millionths | ten millionths | hundred millionths |
| 7 | ||||||||||
| × | 0 | . | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
| . |
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 8 decimal place(s). So once calculated, the result will be reduced by the factor of 100,000,000.
| Place value | ones |
| 7 | |
| × | 1 |
2. Add the partial products
Start by multiplying the ones digit (1) of the multiplier 1 by each digit of the multiplicand 7, from right to left.
Multiply the ones digit (1) of the multiplicator by the number in the ones place value:
1×7=7
Write 7 in the ones place.
| Place value | ones |
| 7 | |
| × | 1 |
| 7 |
Because we have 8 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 8 time(s) to the left (reducing the result by the factor of 100,000,000) to get the final result:
The solution is: 0.00000007
