Question

Plzzz guys, help me with this​

Answer 1

Assosiative property will be used here;

= [-3/4] × 5/4 - 6/7 × [-3/4]

= [-3/4 × 5/4] - [6/7 × -3/4]

= -15/16 - [-18/28]

= -15/16 + 18/28

• On taking l.c.m of 16 & 28 we will get 113, manipulate these two acc. to it.

=( -105+72)/112

= -33/112

Answer 2

Distributive property

Explanation:

-3/4*5/4-(-6/7)*(-3/4)

-15/16-(18/28)

-15*7-18*4/112

-105-72/112

-177/112
