ive been stumped on this for 20 minutes now.
ive gotten this far..
turning mixed numbers into improper fraction:
3x7=24 24+3=27 -> 27/7
2x9=18 18+7= 25 -> 25/9
Multiply across:
27/7 x 25/9= 675/63
Changing improper fraction into a mixed number:
9 75/7
this is where imstumped the answer is 9 11/21
i just dont understand how the 11/21 came into place!
PLEASE HELP!!
