Looks like (12 - 9) / (8/12) + (16 - 12) / (64/2)

Start by simplifying each term:
12 - 9 = 3
8/12 = 2/3
16 - 12 = 4
64/2 = 32
so we now have:
3 / (2/3) + 4 / 32 : you still with me?

simplify again:
3 / (2/3) = 3 * 3/2 = 9/2
4 / 32 = 1/8
so we now have:
9/2 + 1/8

9/2 = 36/8; so we now have:
36/8 + 1/8 = 37/8

Did you follow all that?
QUESTION: do you listen in class? or watch the boys?

Hi thankyou for the help only confused on one issue th / between the 8 and th 12 to include the 64 and the 2 stands for divided by that makes it a little more tricky can you still help?

Hello, Rachael!

. . . . . . . . . . . . . . . . . . . 8
The 8/12 is a fraction: ---- . . . and that's why there is a division.
. . . . . . . . . . . . . . . . . . .12

Two answer your question, there are no boys worth watching in my class....I do pay attention, My teacher just did not explain how to do a problem with fraction line .

Denis, just relax with those comments, ok? This is a MATH FORUM, remember? Let's not make people feel uncomfortable. Another comment like that and you will get detention!

It's nice of you to make the suggestion (thank you!), but, according to another male tutor, men can't help themselves. Their targets need to make allowances.

Ah c'mon happy: you're just jealous because you didn't make

Hey, I'll take detention if it's with stapel;
we can play "spin the bottle" and I'll win every time
if it's with soroban, I'll shoot myself!
