what is 5 x 1 3/5?

OpenStudy (brrandyn):

Convert the 5 into an improper fraction. \[5*5 = 25/5\] Multiply that by converting the one to an improper and adding it to 3/5 \[5/5 + 3/5 = 8/5\] Multiply the improper fractions.

OpenStudy (aaalive):

8?

OpenStudy (brrandyn):

\[\frac{ 25 }{ 5 } * \frac{ 8 }{ 5 } = 8\] You're correct! :)

OpenStudy (aaalive):

yayayay! can you help with some more?

OpenStudy (brrandyn):

Sure.

OpenStudy (aaalive):

what is 3 3/8 x 4 1/3?

OpenStudy (aaalive):

express the answer in simplest form

OpenStudy (brrandyn):

Same scenario, AAALive. Though, find a common denominator for 8 and 3. Post your result and we'll go from there.

OpenStudy (aaalive):

the common denominator is 24, give me a sec to convert them

OpenStudy (aaalive):

so 3 9/24 x 4 8/24=?

OpenStudy (brrandyn):

Nicely done on the conversion! Now, convert the 3 and 4 to an improper. Denominator = /24\[24*3 = 72/24 , 24*4= 96/24\] Add that with your converted and solve for the solution.

OpenStudy (brrandyn):

\[\frac{ 72 }{ 24 } + \frac{ 9 }{24} * \frac{ 96 }{ 24 } + \frac{ 8 }{ 24 } = ...\]
