Decimal Number Problems

Explain Division of Decimals.

When dividing decimals, make sure the ​ (a)   is a whole number. Then, move the decimal point in the ​ (b)   the same number of times.

To solve the problem, Ms. Parker must move the decimal point in the ​ (a)   to the ​ (b)   to get a whole number. This is the same as multiplying by ​ (c)   , so she should also move the decimal point in the ​ (d)   . The correct quotient is ​ (e)   .

Allen is working on this problem. $$42.07\times3.5=$$ ? Allen multiplies the numbers without their decimal points. and then moves the decimal point in the product to find the $$42.07\times3.5=1,472.45$$ . Sally says that his product is incorrect. Drag-and-drop to help Sally explain Allen's error. Allen moves the decimal ​​ (a)   . The first factor has ​ (b)   decimal place(s), and the second factor has ​ (c)   decimal place(s). The product should have ​ (d)   decimal place(s). He should have moved the decimal point ​ (e)   .
