Answer:
Step-by-step explanation:
1) 3/8 + 5/8 = (3+5) / 8 = 8/8 = 1 is the answer.
2) 7/12 - 5/12 = ( 7 - 5 )/12 = 2/12 = 1/6 is the answer.
3) - 2/3 + 1/3 = ( - 2 + 1 ) / 3 = - 1 / 3 is the answer.
4) 3/5 - ( - 1/5 )
= 3/5 + 1/5 ( - × - = + )
= ( 3 + 1 ) /5 = 4/5 is the answer.
5) 9 - 6 1/4 = 9 - 25/4 = ( 4 × 9 ) - 25 / 4 = 36 - 25 / 4 = 11/4 is the answer.
6) 8 4/9 - 2 1/16 = 76/9 - 33/16 = ( 16 × 76 ) - ( 9 × 33 ) / 144 = ( 1216 - 297 ) / 144 =
919/144 is the answer.
7) 7 3/4 + 1 1/8 = 31/4 + 9/4 = ( 31 + 9 ) / 4 = 40 / 4 = 10 is the answer.
8) 9 2/3 - 8 1/9 = 29/3 - 73/9 = ( 9 × 29 ) - ( 3 × 73 ) / 27 = ( 261 - 219 ) / 27 = 42 / 27 is
the answer.
9) 1/4 - 5/8 = ( 2 × 1 ) - 5 / 8 = ( 2 - 5 ) / 8 = - 3 / 8 is the answer.
10) 5 3/4 + 1 2/3 = 23/4 - 5/3 = ( 3 × 23 ) - ( 4 × 5 ) / 12 = ( 69 - 20 ) / 12 = 49 / 12 is the
answer.
