I would recommend changing 3 1/2 into an improper fraction.
So 3 1/2 will become 7/2.
Now we are multiplying 7/2 and 3/4.
Remember when multiplying fraction we say top times top and bottom times bottom.
So we will have (7 x 3) / (2 x 4), which is 21/8.
21/8 as a mixed number becomes 2 5/8.
Hope this helps!

First, change 3 1/2 into improper fraction by multiplying 3 and 2 and 1. So, you will get 7/2. Then, multiply numerators and denominators. 7x3 = 21 and 2/4 = 8. You will get 21/8. Then divide 21 by 8. The quotient will be 2 and the remainder will be 5. You answer is 2 5/8.

Well, 3* 3/4 = 9/4 = 18/8
1/2 * 3/4 = 3/8
Adding these together gives 21/8 = 2 5/8.

2 5/8. Did you know you can Google math problems too? I just put in 3.5 * .75 and got 2.625. That's 2 5/8.
