how do you solve these types of problems

Answer 1

the first three questions are answered as follows
~ = means repeating decimal
#1 $75 - (75 x .333~) = $50
#2 $150 - (150 x .5) = $75
#3 $750 x .1 = $75

the easiest way to the the additional problems you have add is as follows

#1 80 x .2 = 16
#2 50 x .5 = 25
#3 40 x .1 = 4
#4 68 x .25 = 17

Answer 2

75- (75x.333)

150-(150x.05)

750x.10
