Multiply and simplify 2/3*13
The answer is 22. Right?

if you mean

(2/3) * 13

or

2 / (3*13)

i believe according to both your answer is wrong

Is that (2/3)*13? If so, then (2*13)/3= something other than 22. Or if it is
2/(3*13) = it is not 22. Show your work and perhaps we can find your error.

Do you remember how to multiply fractions? It's the easiest process of all the fraction processes! Just multiply across. So ...

2/3 x 13/1 = ??

Please repost and let us know what you get.

I'm sorry I meant 2/3*33= 66/3 or 22.
The answer to 2/3*13 would be 26/3 or
8 2/3. Right?

right -- on both problems

2/3 1.8 Solve for unknown
---- = ----
10 r

2/3 over 10 equals 1.8/r solve for r. this is how the question is posed.
