Q.1 Add the following using suitable property as applicable:
a) 2/7 + (-11/5) + (-3/7) + 3/5
b) -4/9 + (-2/7) + (-5/14) + 3/18​

Answer 1

Answer:

(a)-61/35

(b) -58/63

Step-by-step explanation:

(a) 2/7 + (-11/5) + (-3/7) + 3/5

2/7 + (-11/5) = -67/35

-67/35 + -3/7 = -82/35

-82/35 + 3/5 = -61/35

(b) -4/9 + (-2/7) + (-5/14) + 3/18​

-4/9 + (-2/7) = -46/63

-46/63 + -5/14 = -137/126

-137/126 + 3/18 = -58/63
