A.36
B.64
C.138
D.225

we are told that 75% of a number is 120. So we have to figure that part out first

Answer 43

0.75 x 120 = 90
so now we have 90 we need 40% of 90
converting from percent to decimal
40/100 = 0.40
0.40 x 90 = 36

Answer 44

40 books

@Ddaddysgirl13

Answer 51

36 is incorrect let me explain

Answer 52

told you it's sleep issues and I haven't done these in ages. >_<

Answer 53

so when I was rechecking, I had this odd number that didn't fit, so there must be another method.

Answer 54

\[\frac{ 75 }{ 100}*160=120\] so we use 160 and find 40% of it \[\frac{ 40 }{ 100 }*160=64\]

Answer 55

where did you get 160?

Answer 56

oh x.x misread the question
75% of a number is 120.
0.75 x n = 120

Answer 57

then divide 0.75 for 160

Answer 58

\[\frac{ 100 }{ 75 }*120=160\]

Answer 59

then 160 x 0.40 = 64

Answer 60
