Is this how I would multiply?

like if you have a whole number 3and 1/2yd
multiplied by 4yd.

Would I first multiply the 4x3 = 12 and 1/2? or no?

No.

The easiest way is to change the fraction to a decimal.

3.5 * 4.0 = 14.

Another way is to multiply:

1/2 * 4 = 2
3 * 4 = 12
12 + 2 = 14
oh ok, thanks.
You're welcome.
