To solve this problem, we'll add the numbers 12.75 and 3.35 by aligning them by their decimal points:
Step-by-step:
The sum is . However, since trailing zeroes after the decimal point in a non-fractional number can be omitted without affecting its value, the final answer is given as .
Therefore, the solution to the problem is .
16.1
\( \text{0.6+0}.5= \)
Lining up decimal points ensures you're adding digits in the same place value. Without alignment, you might add tenths to hundredths, which gives completely wrong results!
When adding digits gives you 10 or more, write down the ones digit and add the tens digit to the next column. For example: 7+3+1=11, so write 1 and carry 1.
Yes! Trailing zeros after the decimal point don't change the value. , so both answers are mathematically equivalent.
You don't need to add zeros! Just make sure both numbers have the same number of decimal places by imagining zeros if needed: 12.75 + 3.35 (both have 2 places).
Always double-check by estimating first: 12.75 + 3.35 should be close to 13 + 3 = 16. If your answer is far off, you likely missed a carry operation.
