Nurdine made 2 pans of brownies that were exactly the same size. She cut the first pan into 8 equal pieces. She cut the second pan into 12 equal pieces. She gave 2/8 of the first pan of brownies to Kim. She gave 3/12 of the second pan of brownies to Tyler. Hayze said it wasn't fair because Tyler got more brownies than Kim. Nurdine said they got the same amount. Who is right and why?
Nurdine is right because both 2/8 and 3/12 are equivalent to 1/4.
2/8= 6/24
3/12 = 6/24
6/24 = 6/24
Natalie ate 2/4 of a mini pizza. Brady ate 1/4 of a giant pizza. Their friend, Reagan, says Natalie ate more pizza since 2/4 is bigger than 1/4. Do you agree with Reagan? Why or why not?
No because the area of the mini pizza is much smaller than the area of the giant pizza. 2/4 of the mini pizza may be smaller than 1/4 of the giant pizza. The wholes are not equal so the same parts of each pizza will not be equal.
