Answer 1

Answer:

1) 8 upon 8

2) 2 upon 12

3) 3 upon 3

4) -4 upon 5

Answer 2

Answer:

Step-by-step explanation:

1) 3/8 +5/8 = 8/8 =1 (when the numerator and denominator has the same number that means the answer is one

2)7/12 -5/12 = 2/12 = 1/6 (simplify the fraction by dividing it by 2)

3) it is similar to question one

4) 3/5 - (-1/5) = 3/5+1/5 (negative times negative equals to positive) Final answer is 4/5

5) 9- $6\frac{1}{4}$ = 9- 25/4 (convert into improper fraction), 9/1 (9 is same as 9/1), then multiply by the common denominator which is 4.  {9(4)/1(4) - 25/4} (the bracket means multiply), (36/4 - 25/4 = 11/4) finally make this answer as a mixed fraction as $2\frac{3}{4}$

6) instead of question 6 i will do question 7

7)$7\frac{3}{4} + 1\frac{1}{8}$ -  convert both fractions as mixed fraction like 31/4 +9/8, then you should multiply by the common denominator which is 8, to make it the same multiply by 2 ( 31(2)/4(2) +9/8 = 62/8 +9/8 =71/8 then convert it into a mixed fraction as $8\frac{7}{8}$

( questions 6,8 and 10 is similar to question 7 )

9) 1/4 -5/8 = 2/8-5/8 = -3/8
