Question

Simplify by removing the brackets ;1/3 ÷ { 2/5 X [ 1 1/4 - 3/4 ] – 2}

Answer 1

Answer:

Step-by-step explanation:

2\5 x [11/4 -3\4] -2

11\4 - 3\4

=8\4

=[2\5 x 8\4] -2

= lcm of 5,4 =20

[2\5 x 4\4 ] x [8/4 x 5\5]

8\20 x 40\20

=320/20

so ,it is a improper fraction we need to turn it into mixed fraction

= 320 divided by 20

= 16

so, 2/5 x [11/4 - 3/4 ]-2

=16
