Please solve my problems b &d

Dear Student,


b)
Multiple of 15 that are smaller than 50

are:-
15*1=15
15*2=30
15*3=45
15*4=60 which is bigger than 50

So,

Multiple of 15 that are smaller than 50 =15,30,45



d)
Multiple of 100 are:-

100*1=100
100*2=200 which greater than 150


So,
Multiple of 100 that are between 0 and 150 are 100 only
