Hi Dianne,

Let me try a similar problem,

I am going to evaluate the three parts separately

8 × 5 - 4: We always multiply before adding so this is 40 - 4 = 36.
3 × 5: This is 15.
7 × 2 - 8: Again, multiply first and get 14 - 8 = 6.

Thus

What I see now is that 3 divides 36 (36 = 3 × 12) and 3 divides 15 (15 = 3 × 5) and thus

But this is one-sixth of 12 divided by 5 and hence

Finally both 6 and 12 are divisible by 6 and thus

Now try your problem and write back if you need more help.
