Can someone help me with this question? http://imgur.com/a/v9vwg

Earlier you found that \[\Large 2\frac{5}{6} = \frac{17}{6}\] Once that step is done, you just multiply straight across (numerators pair up and multiply, so do denominators) \[\Large \frac{3}{5}\times2\frac{5}{6} = \frac{3}{5}\times\frac{17}{6}\] \[\Large \frac{3}{5}\times2\frac{5}{6} = \frac{3\times17}{5\times6}\] \[\Large \frac{3}{5}\times2\frac{5}{6} = \frac{51}{30}\] \[\Large \frac{3}{5}\times2\frac{5}{6} = \frac{17}{10}\] Don't forget to reduce fully. Then you can convert that result into a mixed number. Let me know if you need help doing that.

Whats the answer

OpenStudy (nortexplay):

erm

jimthompson5910 (jim_thompson5910):

do those steps make sense?

OpenStudy (nortexplay):

yes they do....

jimthompson5910 (jim_thompson5910):

Do you know how to convert `17/10` to a mixed number?

OpenStudy (nortexplay):

wait

OpenStudy (nortexplay):

yes

OpenStudy (nortexplay):

it's 7/10

jimthompson5910 (jim_thompson5910):

close but not quite

OpenStudy (nortexplay):

halp

OpenStudy (nortexplay):

me

jimthompson5910 (jim_thompson5910):

\[\Large \frac{17}{10} = \frac{10+7}{10}\] \[\Large \frac{17}{10} = \frac{10}{10}+\frac{7}{10}\] \[\Large \frac{17}{10} = 1+\frac{7}{10}\] \[\Large \frac{17}{10} = 1\frac{7}{10}\]

OpenStudy (nortexplay):

okay

jimthompson5910 (jim_thompson5910):

Or you can think of it this way 17/10 = 1 remainder 7 the quotient of 1 is the whole part, the remainder 7 is the numerator over the 10

OpenStudy (nortexplay):

thats 27/10

OpenStudy (nortexplay):

i need help

jimthompson5910 (jim_thompson5910):

So what this all means is that \(\Large \frac{51}{30}\) is equivalent to \(\Large \frac{17}{10}\) which is equivalent to \(\Large 1\frac{7}{10}\) All of those expressions are equivalent to the original expression.

OpenStudy (nortexplay):

so is the answr b and d?

OpenStudy (nortexplay):

and c?

OpenStudy (nortexplay):

i have a time limit

OpenStudy (nortexplay):

hello

jimthompson5910 (jim_thompson5910):

let me check

jimthompson5910 (jim_thompson5910):

yes, B, C and D are the answers. Only choice A is the non-answer

OpenStudy (nortexplay):

wait

OpenStudy (nortexplay):

can you help me with 1 more and thats it

jimthompson5910 (jim_thompson5910):

ok one moment

jimthompson5910 (jim_thompson5910):

are you able to convert those mixed numbers to improper fractions?

OpenStudy (nortexplay):

idk

OpenStudy (nortexplay):

help

jimthompson5910 (jim_thompson5910):
