Multiplying and Dividing Mixed NumbersDate: 6/5/96 at 18:53:41 From: Anonymous Subject: Multiplying / dividing mixed numbers Dear Dr. Math, I need help on multiplying and dividing mixed numbers - like 1 1/2 divided by 9/10 or 8 1/4 x 2 2/3 or 3 1/2 x 2/7 x 4. It's like those.

So 1 1/2 = 3/2 and multiplied by 9/10 gives (3/2)*(9/10) = 27/20 = 1 7/20 (8 1/4)*(2 2/3) = (33/4)*(8/3) = (33*8)/(4*3) = 11*2 = 22 (3 1/2)*(2/7)*(4) = (7/2)*(2/7)*(4) = 4 -Doctor Anthony, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
