Answer:
18 3/4
Step-by-step explanation:
Solve {(32)-3/4)3/4}4/5
Expand the inner parenthesis
{(32)-3/4)3/4}4/5
= {3/4(32) - (3/4)(3/4)}*4/5
= {3(8)- 9/16} * 4/5
= {24 - 9/16}* 4/5
= 4/5(24) - 4/5(9/16)
= 96/5 - 36/80
= 96/5 - 9/20
Fine the LCM
= 96(4)-9/20
= (384-9)/20
= 375/20
= 18 15/20
= 18 3/4
Hence the required result is 18 3/4
