CAN I MULTIPLY DECIMALS? The answer is the picture on the right, 3 sets of 0.22 = 0.66 Nicole spends $15.74 on school supplies. Sally spends 4 times as much as Nicole. How much does Sally spend? $15.74 X 4 = $20 x 4 = $80 as an estimate. $15.74 X 4 _______ $62.96 So, Sally spends $62.96 on school supplies. I hope she shares with everyone else. I know that if I multiply by 10, I will move the decimal point one place to the left. I want my number to get bigger. 0.48 turns into 4.8. So, Denise uses 4.8 meters of ribbon 8.35 x 5 = 8 x 5 as an estimate, so that is 40 miles. 8.35 X 5 ____ 41.75 So, Chareese drive 41.75 miles in 5 days. Angela knows that 3.4 grams = 1 dime. She has 3 dimes. How much do her 3 dimes weigh? 3.4 x 3 = 3 x 3 as an estimate, so that is 9 grams. My answer should be more than 9 grams, but close. I can distribute 3 and 0.4. So, (3 x 3) + (3 x 0.4) = 9 + 1.2 = 10.2 grams I need to show the expanded form for 36 x 0.26 as an expresssion. So, I can make 36 into 30 + 6. I can make 0.26 into .2 + .06 Therefore, (30 + 6) x (.2 + .06) would be my expression in expanded form. I don’t need to find an answer when it is an expression. First, I need to solve the problem, because the PRODUCT is the answer to a MULTIPLICATION problem. My factors are 3.5 and 1.73 I put 1.73 on top of 3.5 because it have more digits. 1.73 X3.5 _____ 6.055 So the place value of the decimal in the product is thousandths What does Debbie’s model show? 0.2 0.04 20 5 A. 20.2 X 5.04 B. 20.5 x 42 C. 25 X .24 D. 2.5 X 24 The answer is C A. 100 X .36 = 36 B. 10 X 3.6 = 36 C. 10 X 36 = 360 D. 100 X 0.36 – 3.6 The answer is A Judy $6.78 Brooke $6.78 $6.78 $6.78 A. 0.1 X 2,844 = 284.4 B. 0.001 X 2,844 = 2.844 C. 10 X 2,844 = 28,440 D. 1.0 X 2,844 = 2m844 The Answer is A. The answer is 2 X 0.22
