What is 2/5-1/3 fractions

You have to make the denominators (bottom numbers) the same via multiplication, it's best to do it to the first number they meet at. that would be fifteen (15)

5*3=15

3*5=15

you then have to multiply the numerators by the respective numbers.

2*3=6

1*5=5

you then subtract the numerators normally

6-5=1

slap back on the denominator

1/15

there's your answer.

(the number you multiply them by isn't the other denominator, it just happens to be the denominators for this equation)
