Question

Ted says that 3/10 * 100 equal 300000 is he correct use a place value chart to explain your answer

Answer 1

No. The right answer would be 30. 3/10 is 0.3, a decimal in the tenths, 100 is a number in the hundreds, their product will most likely be a number in the tens (as 0.1x100=10).

Answer 2

No, 3/10 * 100 = 30

Explanation:

You have to calculate 3/10 * 100 in three steps. First rewrite 3 as 3.0; nothing changes, in this way the procedure is easier. Then, divide 3.0 by 10. To divide by 10 you have to move the decimal point one step to the left. So, 3.0/10 = 0.30, or just 0.3. Now you have to multiply 0.3 by 100. To multiply by 100 you have to move the decimal point two times to the right. So, 0.3*100 = 30.0 or just 30.
