3 3/7*2 7/12

(24/7) * (31/12) = ?
Okay first make them improper. You do this by multiplying the denominator with the whole number and then you add it with the numerator. So:
3 3/7= 3x7=21+3=24. . .24/7
2 7/12= 2x12=24+7=31. . .31/12
Now find a common denominator. This means you must find a number that the denominators 7 and 12 share. 84 is the denominator this time because I multiplied 7 and 12 to get the it. Whatever you do to the bottom you do to the top. Sooooo, 24/7 becomes 288/84 and 31/12 becomes 217/84.
Now, to add this but only the numerators.
288+217=505
505/84:::Divide them both by a reasonable number. If you can't divide it (like right now) then make it into a mixed number. You make an improper into a mixed by seeing how many times 505 goes inside 84. 6 1/84 is your final answer!

I got 8 6/7
(24/7) * (31/12) = 744/84 = 8.857 = 8 6/7
You're right, Ash! :-)
