- How to compare decimals to the thousandths.
- How to round decimals using our knowledge of place value.
- And we’ll see how this knowledge can help us weigh diamonds, test our reaction time, and even have a garage sale.
- Discussion Questions
Before Video
How many ones, tenths, and hundredths are there in 7.39?ANSWER7 ones, 3 tenths, 9 hundredths.
0.6, 0.03.
Twenty-nine hundredths is 2 tenths and 9 hundredths, so 1.29.
Yes, 36 = 30 + 6, and 30 hundredths can be regrouped as 3 tenths. Then we have 3 tenths and 6 hundredths.
There are 10 hundredths in every tenth, so 8 tenths is 80 hundredths.
After Video
How can you say 9.127 using words? ANSWERNine and one hundred twenty-seven thousandths.
The hundredths place tells me that 3.679 is greater.
Since 5.78 has no value in the thousandths place, I can just write 0. 5.78 is the same as 5.780. Since 1 is greater than 0, 5.781 is greater than 5.78.
The thousandths place shows that 2.588 is greater than 2.583, so Hana took more time. That means that Zoe did her homework faster.
Because 4.719 is closer to 4.72 than 4.71, I round up. The number in the hundredth place changes. 4.712 is closer to 4.71 than to 4.72, so the number in the hundredths place does not change and the rounded number is 4.71.
