anonymous · Answer

Haha yeah, this question is on a practice test that i just can't seem to figure out!

anonymous · Answer

well let's do$$14 * 50 \frac{ 6 }{ 7 }$$

anonymous · Answer

Wouldn't you have to turn the mixed number into a improper fraction?

anonymous · Answer

712 grams

anonymous · Answer

i figured you would do that during your work x]

anonymous · Answer

UCL how did you get that answer!

anonymous · Answer

this is why the rules say don't just give the answer -.-

anonymous · Answer

356/7 is the improper fraction

anonymous · Answer

$$50 \frac{ 6 }{ 7 }$$
$$\frac{ 356 }{ 7 } * \frac{ 14 }{ 1 } = \frac{ 4984 }{ 7 }$$
simplify that to 712

anonymous · Answer

Oh.. that might be what i did wrong, i reduced the 7 to 1 and turned the 14 into 7

anonymous · Answer

well you can cross cancel

anonymous · Answer

356 * 2 = 712

anonymous · Answer
