how to do help pls

So for numbers from 100 to 150,

First multiple of 4 in this range is 100 (4 X 25 = 100)
Last multiple of 4 in this range is 148 (4 X 37 = 148)

So that gives us 35 - 25 + 1 = 11 multiples of 4 in the range

Similarly Try 5 and let me know if you want any help

For c you need to find how many are multiples of both four and five and subtract that number from the sum of the answers to a and b

can u do it

[lilac cloud]

any number that is a multiple of both four and five will be a multiple of 4*5 so a multiple of 20

so u can do the same process for multiples of 20

then subtract that
