At the beginning of the month, there were 80 ounces of peanut butter in the pantry. since then, the family ate 0.3 of the peanut butter. how many ounces of peanut butter are in the pantry now ?

79.7

Step-by-step explanation:

Ok, this is very simple, but we can go through it step by step =)

In words, there were 80 ounces of peanut butter, and 0.3 of those ounces were taken away (eaten). Now put it into mathematical terms:

80.0 - 0.3

To subtract a decimal, you need to line up the decimals and put a decimal in the difference in the same place as the minuend and subtrahend. Then solve like a normal subtraction problem.

80.0

-  0.3

79.7

I really hope this helps =)
