Multiplying mixed numbers
Example : 2 3/4 x 3 2/8
Get MAD!!! Not angry MAD =
Multiply, Add , Denominator
2 3/4, multiply the denominator (4) by the whole number (2), add the numerator (3) and then keep the denominator 4*2+3=11
So....my new MAD fraction is 11/4.
3 2/8 do the same thing. 8*3+2(MAD)=26
Keep the denominator =26/8.
My new problem is now 11/4 *26/8. Now I multiply the numerators (11*26 ) the n multiply the denominators (4*8) My answer is 286/32 I can't keep it like this because it's improper . I divide the numerator by the denominator . 286 divide by 32 is 8 with 30 left over. My answer is 8 30/32. But wait there's more !! I can simplify the fraction. I can divide the denominator and numerator by 2. My final answer is 8 15/16.
