Writing to Explain Explain how to subtract 7.6 from 20.39.

Sagot :

Answer:

12.79

Step-by-step explanation:

The question is asking for you to subtract 7.6 from 20.39

The equation is 20.39-7.6=n (n represents a number or difference of the equation)

1.) When writing the equation down to solve, align the decimal points to each other meaning the 0 in 20.39 has 7.6 under it!

 20.39

-   7.6                (Note the bold numbers are showing the decimal point aligned)

2.) Fill in places that have missing digits with a 0 meaning when you aligned the numbers, the number 9 doesn't have anything to subtract with so you should fill it with a 0

 20.39

-   7.60  (Note there has been a 0 added to 7.6 once it was aligned)

3.) Subtract regularly!

20.39-7.60=12.79

Therefore the answer to this question is 12.79
