Aida is working on the multiplication problem 76.7 x 6.23. She multiplies 767 × 623 to get 477841, but isn't sure where to place the decimal point. How can she reason about the size of the factors to decide where the decimal goes? (She doesn't know the rule about counting decimal places, and you're not there to tell her, and you will get no credit for your answer if you refer to that rule.)

On a blank sheet of paper (lined or not), write any two different positive integers less than 10. In other words, two different single digit positive whole numbers. (Yes, that is redundant because whole numbers are positive.) Use those two numbers to create two factors, (x- a) and (x - b), where a and b are your two numbers. (If you work together with others on this, which is ok for this assignment, be sure each of you chooses different numbers.) Multiply your factors to create a quadratic in standard form. Next write as a function: f(x) = x^2 - bx + c Now create a quadratic equation by changing f(x) to zero: O = x^2 - bx + c
When lupe was aksed to factor 26x55 into a product of prime numbers, she first multiplied 26x55= 1,430, and then proceeded to make a factor tree for 1,430 bt first writing 1430 as 2x715 and then looking for factors of 715. Write how you help Lupe factor 26x55 into a product of prime numbers without doing the multiplication to the larger product.
