4th Grade Math: Help Is Needed ASAP
posted by Tim .
My son is in the fourth grade and is needing help with these math problems. Can someone please help him with these problems.
1. 2/3+2/9=
2. 3/5+3/10=
3. 5/12+1/3=
4. Find the sum of 1/6 and 1/12
5. Add 1/4 to the answer in Exercise 4.
6. What is the sum of 1/8, 1/4, and 3/8?
7. Add 1/3, 3/12, and 5/12.

He needs to change one of each pair of fractions so that they have a common denominator.
2/3 + 2/9
Then add the numerators.
6/9 + 2/9 = 8/9
