Mai says that 7×0.4 and 7×0.04 both have the same value. She says that they are both 28.
Do you agree with Mai? Show and explain your reasoning.
Mai is not correct. She is right that there are 28 in both cases, but for 7×0.4 it's 28 tenths and for 7×0.04 it is 28 hundredths. So 7×0.4=2.8 and 7×0.04=0.28.
