how much more is 18p + 17p than 2 * 15p?

"how much more" implies subtraction.

How much more is 10 than 6?
answer: 10-6 = 4

So, her we have to do

(18p+17p) - (2*15p)
= 35p - 30p
= 5p

work out 72/6 =

what, you have no calculator?

In any event, 72/6 is a value. Nothing there to "work out". It can, however be simplified by noting that

72/6 = 6*12/6 = ...

To find out how much more 18p + 17p is than 2 * 15p, we first need to simplify the equations.

Starting with 18p + 17p:
Combine like terms by adding the coefficients (numbers in front of the "p"):
18p + 17p = (18 + 17)p
18p + 17p = 35p

Now, moving on to 2 * 15p:
Multiply 2 with 15p to get the value:
2 * 15p = 30p

To find how much more one quantity is than another, we subtract the smaller value from the larger value:
35p - 30p = 5p

Therefore, 18p + 17p is 5p more than 2 * 15p.
