Question

Winnie has 1/2 cup of flour in a mixing bowl.she adds more flour. winnie claims that she now has 3/7 cup of flour in the mixing bowl. Which statement explains why winnie’s claim is incorrect

Answer 1

First, let's make 1/2 and 3/7 have the same denominator to make it easier to see. We know that there Least Common Multiple (LCM) is 14.

1/2=7/14

3/7=6/14

Wait a second... 3/7 is less than 1/2. This means that Winnie's statement is false because it is impossible that after adding more flour, she actually has less flour than what she started with.

Hope this helps! :)
