Marcia said that if she estimates 73 x7, the product will be less than the exact answer. Is she correct? Explain.

    I think:

    it depends. If you round 73 and 7 then the estimate will be larger than the actual value(70*10=700 is larger than 73*7=511) if you on round 70 than the estimate will be smaller (70*7=490).
