Video Notes Record all of the following notes from the video in your math notebook..3 X .7 =.63 X 2.8 =2.6 X 1.4 =4.5 X .08 = Show me what you know! Solve each problem. .6X .2 .33X .8 1.7X .22 Show me what you know! Complete the table. The digits in the solution are given to you. Just rewrite the answer in the solution box placing the decimal point in the correct place. Problem: Solution: 1.8 X .9 = 162 1.62 .03 X 1.6 =0048 0.048 4.2 X 4.2 = 1764 17.64 11.1 X .8 = 888 8.88 Show me what you know!Write an estimated problem and solution for 1.16 X .4. Now solve the actual problem making sure to correctly place the decimal point in your answer. Place in your answer box. This method of using properties is the ONLY way to solve a multiplication problem with decimals. True False Which of the following expressions is equivalent to .4 X .3? Only one will be true, and all others should be marked false.(4 X 1 X (3 X 1 True False (4 X 10) X (3 X 10) True False (4 X 1 X (3 X 1 True False (4 X 1 X (3 X 1 True False
