Question

Jerry has 7 3/4 dozen donuts. He purchased another 4.25 dozen donuts. How many dozens of donuts does he have now?

Answer 1

12 dozen

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 2

12 dozens of donuts

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.
