    1/12

    Step-by-step explanation:

    25% is equivalent to 1/4

    hence Mary understands 25% = 1/4 of her homework

    given that Joe understands 1/3 as much as Mary

    = 1/4 x 1/3

    = 1/12

    hence Joe understands 1/12 of the total homework.

    8.3%

    Step-by-step explanation:

    get 25% as a decimal

    25/100=.25

    get 1/3 as a decimal

    1/3=.33333

    multiply the decimals together

    .33333x. 25=.08333

    multiply this decimal by 100

    .08333x100=8.3%
