15 : 75
x : 100
cross multiply

anonymous · Answer

15 is 75% (i.e. 3/4) of S, his scheduled hours

15=0.75S

S=15/0.75=20

75% is 3 out of 4

15/3 = 5 ;  5*4 = 20

amistre64 · Answer

if 15 units is 75%; then divide 15 by 75 to determine 1%;

the value at 1% is multiplied by 100 to get the total amount
