how do I multiply 18 x 3/5=
18/1 x 3/5, do i find common denominator, then straight across?
For multiplying, you don't need to find a common denominator. Just multiply both numbers across. You'll get
18 x 3 over 5 (since 5 x 1 = 5).
What do you get?
??
54 over 5
Yes, now divide 54 by 5. What do you get?
10 4/5, thanks
You're welcome.

To multiply fractions, you generally multiply the numerators (top numbers) together and multiply the denominators (bottom numbers) together. In this case, you have the fraction 3/5 and the whole number 18.
To multiply 18 and 3/5, you can convert 18 to a fraction by placing it over 1: 18/1. Then, multiply the numerators together (18 x 3) and the denominators together (1 x 5).
So, multiplying 18/1 and 3/5 gives you (18 x 3) / (1 x 5) = 54/5.
However, if you want to find the answer in simplest form, you should reduce the fraction. In this case, 54/5 cannot be simplified further, so the answer is 54/5 or 10 4/5.
