6. 3 3/8+6 5/8=10
7. 11/14-3/14= 8/14
8. (-1/8)-5/8=-3/4
9. 4/12-10/12=-1/2
Right.
10. Hank was 62 1/8 inches tall at the end of school in June. He was 63 7/8 in September. How much did he grow during the summer? 1 3/4
11. 2/5+1/5=3/5
12. 3/10+7/10=1
13.(-3/4)+(-3/4)= -1 1/2
14. (-13/16+(-9/16)=1 5/16
15. 7 2/5+4 2/5= 11 4/5
16. 5 17/20+5 9/20= 11 3/10
17. 5 7/9+ 3 5/9=9 1/3
14. No.
The others are correct.
1 3/8
The answer for 14 is a negative.
I got -22/16 and I divide it to get a mixed number
-22/16 = -1 6/16 = -1 3/8
To calculate these arithmetic problems involving fractions, you can follow these steps:
6. To add fractions with different denominators like 3/8 and 5/8, first, make sure both fractions have the same denominator. In this case, the common denominator is 8.
So, 3/8 becomes (3/8) * (8/8) = 24/64, and 5/8 becomes (5/8) * (8/8) = 40/64.
Now, add the two fractions: 24/64 + 40/64 = 64/64.
However, 64/64 is the same as 1 whole, so the final answer is 10.
7. To subtract fractions with the same denominator, subtract the numerators while keeping the denominator the same. In this case, the denominators are already the same (14), so we subtract the numerators: 11 - 3 = 8.
Therefore, the answer is 8/14, which can be simplified to 4/7.
8. To subtract fractions, you need to have the same denominator. The denominators in this case are already the same (-8), so we subtract the numerators: (-1) - 5 = -6.
The answer is -6/8, which can be further simplified to -3/4.
9. Similar to problem 7, when subtracting fractions with the same denominator, subtract the numerators and keep the denominator the same. In this case, the denominators are already the same (12), so we subtract the numerators: 4 - 10 = -6.
The answer is -6/12, which can be simplified to -1/2.
