Answer

3(9-3x+5y)

Step-by-step explanation:

So to factorise 27-9x+15y you need the HCM (highest common factor) of 27, 9 and 15.

HCM: 3

So you divide each of the numbers by 3 and you get

27 divided by 3= 9

9 divided by 3= 3

15 divided by 3= 5

So you take the HCM (3) and then the numbers divided by it and put it into brackets

3(9-3x+5y)
