Sophia says that 3/4 and 7/8 are equivalent fractions.
Do you agree with her?
Why or why not?
No, I don't agree. Sophia is not correct. Example answer: I divided these two circles into fourths and eighths to show the two fractions. You can see they are not equal.
Sophia has to multiply 5 x 80. She says she can find 5 x 8, then multiply the product by 10.
Do you agree with Sophia?
Why or why not?
Yes, I agree. Example answer: Sophia is correct because 5 x 8 is 40 and then 10 groups of 40 is 400.
