    11/20

    Step-by-step explanation:

    first find a common denominator

    choices could be 20 or 40

    let's use 20

    how many times does 4 go into 20? 5 times

    1/4 = 5/20

    how many times does 10 go into 20? 2 times

    3/10 = 6/20

    now we can add the fractions because they have a common denominator

    5/20 + 6/20 = 11/20

    this can not be simplified.

    1/4 + 3/10

    find the common denominator which is 20

    multiply by 5 for 1/4

    1 (5) / 4 (5) = 5/20

    multiply by 2 for 3/10

    3 (2) / 10 (2) = 6/20

    5/20+6/20=11/20

    answer:

    11/20
