Answer 1

42.24 is the answer. Hope I helped you!

Answer 2

answer = 42.24

As if in 5.28 there are two numbers after the decimal.

so 5.28 x 0.8 = 4.224

then in 52.8 there is one no. after the decimal.

hence, we will take one no. after the decimal and make it before the decimal.

Therefore 4.224

will become

42.24
