    Answer:

    12 dozen

    Step-by-step explanation:

    • Relatively easy stuff, just recall fractions
    • A dozen means  12
    • he has 7 dozen (7 x 12=84) and 3/4 dozen (3/4 x 12=9) so that’s 84+9= 93 donuts
    • he gets 4.25, which is the same as 4 1/4, so its 4 dozen (4 x 12=48) and 1/4 dozen (1/4 x 12=3) so that’s 48+3= 51 donuts
    • Add what you got 93 + 51 = 144 donuts
    • Then divide this by 12 to get the number of dozens
    • 144/12 = 12 dozen

    Answer:

    12 dozens of donuts

    Step-by-step explanation:

    First, you want to change the decimal into a fraction. The decimal, 4.25, is the same as 4 25/100. You can reduce 4 25/100 to 4 1/4 by diving both the numerator and denomiator by 25.  Now that both of our numbers are fractins, we can just add the fractions up. 7 3/4 + 4 1/4 = 11 4/4 = 12\

    Jerry got 12 dozens of donuts.
