Read through the answers below. If you missed any questions, review this section and then try the additional practice. (NOTE: There are no detailed solutions to this practice.)

1. Complete the following addition problems.
1. 26.86 + .925 = 27.785
 Remember to line up the decimal points. Notice that when you add the digits in the  tenths place (8 +9 = 17) you must carry a 1 to the ones place.

1. 19.034 + 2.67 = 21.704
 One way to line up the decimal points is to add zeros where one number does not have a digit. (2.67 = 02.670)

2. Complete the following subtraction problems.
1. 20 - 11.95 = 8.05
 Remember to line up the decimal points. In this problem we must carry numbers all the way from the 2 in 20 to be able to complete the subtraction.

1. .34 - .287 = .053
 In subtraction, adding zeros as place holders is essential. Notice how we need to add the zero at the end of the .34.

3. Complete the following multiplication problems.
1. .38 x 1.6 = .608
 Remember, do the multiplication as if these were whole numbers. When you are done, count out the decimal places. 2 places for .38, one place for 1.6 gives three decimal places in our answer.

1. 24.55 x .004 = .0982
 In this example, we only need to multiply 2455 by the 4 to get 9820. Then we add on the 5 decimal places needed to get the 0.09820 Note we have to add another 0 before the decimal point to have enough places.

4. Complete the following division problems.
 First set up the traditional division equation. Shift the decimal point over the required number of places so the divisor is a whole number. Perform the division as usual. becomes

 When we move the decimal point over two places, so that the divisor of 0.02 is a whole number, the dividend still has a decimal. The decimal point in the answer is directly above the decimal point in the dividend. becomes:
