Question

r over 12 = 1 9/10 solve for r

Answer 1

\(\huge\frac{r}{12} = 1\frac{9}{10}\)

Is this it?

Answer 2

yeah

Answer 3

Cross multiplication?

Answer 4

You multiply 12 to 1 9/10:

\[12 \times \frac{9}{10} = 22 \frac{4}{5} \]

Answer 5

^Cross multiplication

Answer 6

114/5

Answer 7

In your shoes I'd convert 1 9/10 to an improper fraction before doing that cross multiplication:

1 9/10 = 19/10

Answer 8

Oh

Answer 9

Then,\[\frac{ r }{ 12 }=\frac{ 19 }{ 10 }\]

Answer 10

still stuck

Answer 11

What is the goal of this problem? Explain the goal in your own words. Have you done similar problems in the past?

Answer 12

\(\huge\frac{ r }{ 12 }=\frac{ 19 }{ 10 } = 10r = 228?\) @mathmale

Answer 13

@iGreen: You're on the right track, except that that 2nd = sign should not be in there (use an arrow instead). Please, let qdbug have time to solve this problem himself / herself, OK?

Answer 14

Oh, right...

Answer 15

im still stuck im sorry

Answer 16

Well since

\(\Large\frac{ r }{ 12 }=\frac{ 19 }{ 10 } \LARGE\rightarrow 10r = 228\)

Can you figure out \(10r = 228\)?

Answer 17

First of all, @qdbug, please stop saying "I'm stuck." Instead, think of questions to ask that might produce the info you need to solve this problem, and share those questions, even if you don't think they're good questions.

@gdbug, again I ask you to explain in your own words what the goal of the present problem is. Once you have that goal in mind, we can discuss how to get there.

Answer 18

@qdbug: a question for you: what does "cross multiplication" mean?

Answer 19

Answer 20

If you're satisfied with your brother's explanation, good. If not, come back here, answer my questions, and then we'll continue in finding the solution.
