## Add Fractions with Decimal Sums

Directions: Using the digits 1 to 9 at most one time each, place a digit …

1. My fifth grade student was super proud she found 9 ways so far to complete this! She wanted me to post it here . Thanks!

I found out 20 ways to do this problem! Here are some ways:

4.8+3.1=7.9

3.2+4.7=7.9

7.1+2.3=9.4

1.5+2.4=3.9

8.3+1.4=9.7

3. I am in 5th grade and i found 3.4+5.2=8.6

4. I am in 4th grade and going to fifth grade after summer break. I found a lot of ways, on of them is 1.4+6.5=7.9

5. I am in Sixth grade and this is so good and fun to solve
