Answers
Answer:
) 15/11 + -25/11
15/11 - 25/11= -10/11
b) -1/2 +5/11
= -11/22 + 10/22
= -1/22
c) -5/7+ -4/9
= -45/63 -28/63
= 73/63
d) 13/4 +25/9
= 117/36 + 100/36
= 217/36
e) 21/11 +- 13/8
=168 /88 - 143/88
= 25/88
f) 3/4 +5/6+7/8
= 18/24 + 20/24 +21/24
= 59/24
g) 2/3+ 3/4 -5/12 -1/8
= 16/24 + 18/24 - 10/24 -3/24
= 34/24 - 13/24
= 21/24
h) 3/8 × 16/27
= 2/9
i) -13/19 × -4/13
= 4/19
j) 3/5/13 - 1/1/2
= 3/5 × 1/13 - 1/1 × 1/2
= 3/65 - 1/2
= 6/130 - 65 /130
