Question

48x + 32y/32

I have 48x/32 & 32y/32 = 3x/2 + 2y/2 = 3x/2 + y

Am I working this correctly?

Also 25a + 5b + 15c/10
would I be correct to divide by 5?

Answer 1

You must use brackets to establish the correct order of operation.
According to your steps, the question was:

(48x + 32y)/32

= 48x/32 + 32y/32
= 3x/2 + y

you have the correct answer.


<Also 25a + 5b + 15c/10
would I be correct to divide by 5?>

yes, but again you will need brackets.
The way you typed it, only the 15c is divided by 10

(25a + 5b + 15c)/10
= 5(5a + b + 3c)/10
= (5a + b + 3c)/2
or
= 5a/2 + b/2 + 3c/2

either answer is correct.

Answer 2

You are correct
