Question

Trudy wants to multiply 66×606. She says that all she has to do is find 6×606 and then double that number. Explain why Trudy's method will not give the correct answer. Then show how to find the correct product.

Answer 1

6x2 is not 66, you would need to multiply by 11 instead of 2 because 6x11 is 66 thus getting the correct answer!!!! Hope this helps.
