Answer 2

6 / 4
9.5 / 7

Tell me what you get.

Answer 3

okay give me a second

Answer 4

1.5

Answer 5

1.5

Answer 6

Yep, that's what you get for 7.5

Answer 7

get for 7.5 / 5 and 6 / 4*

Answer 8

what

Answer 9

Nothing..just divide the last one.

Answer 10

1.357

Answer 11

Yes..so we know that there's something wrong with 9.5 / 7..because it doesn't equal 1.5 like the rest..

So we can set up the equation:

\(\dfrac{x}{7} = 1.5\)

Can you solve that for 'x'? Just multiply 7 to both sides..what's 7 * 1.5?

Answer 12

10.5

Answer 13

so its b?

Answer 14

???

Answer 15

Yep, we have to change RQ to 10.5..so 10.5 / 7 = 1.5.
