Question

(-2+5)+(-3+8)+(-9-3)+(-7-2)​

Answer 1

Answer:

you can get from here

Step-by-step explanation:

Solve:

(i) 2 – 3/5 (ii) 4 + 7/8 (iii) 3/5 + 2/7 (iv) 9/11 – 4/15 (v) 7/10 + 2/5 + 3/2

(vi) 2 + 3 (vii) 8 - 3

Answer:

(i) 2 – 3/5 = 2/1 – 3/5

= (2 * 5 – 3 * 1)/5 [LCM (1, 5) = 5]

= (10 - 3)/5

= 7/5

= 1

Answer 2

$\bf \color{red}-13$

Step-by-step explanation:

$\bf=(- 2 + 5)+ (- 3 + 8)+ (- 9 - 3)+ (- 7 - 2)$

$\bf=( 3) + (5) + ( - 12) + ( - 9)$

$\bf=3+ 5 - 12 - 9$

$\bf=8 - 12-9$

$\bf =\color{red}-13$
