You can put this solution on YOUR website! Multiplying fractions:
Multiply across the top, multiply across the bottom, then simplify! Easy!
So let's look at your problem.
Multiplying the numerators (top numbers) gives 2*10=20
Multiplying the denominators (bottom numbers) gives 5*3=15
So now we have we can divide top and bottom by 5, giving OR as a mixed number we have (one and one third)
