Need help with adding subtracting decimals.
In this unit, you learned about fractions that can be written as terminating decimals and fractions that can be written as nonterminating decimals. Create an addition word problem and a subtraction word problem using fractions. Show how to find the solution to each problem. Once you find the solutions to your problems, rewrite the solutions as either a terminating or nonterminating decimal.
Hi bobpursley!
I can take it from here thank you!

Sure, I can help you with that! Let's start with an addition word problem using fractions:
Word Problem: Sarah has 3/4 of a pizza left, and she shares it equally with her two friends. What fraction of the whole pizza does each person get?
To solve this problem, we will add the fractions. The fractions we need to add are 3/4 and 1/4.
Solution:
3/4 + 1/4 = 4/4
The solution to the addition is 4/4. Now, to rewrite this solution as a decimal, we can divide the numerator by the denominator:
4 ÷ 4 = 1
The decimal form of the solution is 1, which is a terminating decimal.
Now, let's move on to a subtraction word problem using fractions:
Word Problem: John had 5/6 of a pie, and he ate 2/6 of it. How much pie does he have left?
To solve this problem, we will subtract the fractions. The fractions we need to subtract are 5/6 and 2/6.
Solution:
5/6 - 2/6 = 3/6
The solution to the subtraction is 3/6. Now, to rewrite this solution as a decimal, we can divide the numerator by the denominator:
3 ÷ 6 = 0.5
The decimal form of the solution is 0.5, which is a terminating decimal.
In summary, for the addition problem, the solution in decimal form is 1, and for the subtraction problem, the solution in decimal form is 0.5.
do this:
4/5 + 19/20= ?
combine the fractions, divide the numerator of the improper fraction by the denominator to see if it is repeating, or non repeating.
