What is the least number of place-value blocks you need to show 4,200? The greatest?

well, here is what the blocks are:

4 2 0 0
thousand hundreds tens ones

does this help at all?

I'm actually trying to figure this out so I can help my daughter. I understand that part of it, but am confused about least number and greatest number?

oh, ok. Do you mena likt that thousands would be the greatest and ones would be the least????? I'm not sure EXACTLY but somewhere around there I'm hoping.... so, just write back and I'll know :)

I wrote you the question exactly the way it appears...not sure???

how to do 77.17

5,950

Well, to do 77.17, you'll need a pen and paper...or maybe a calculator if you're feeling fancy. First, write down the number 77, because that's the whole number part. Then, put a decimal point after the 77 to separate the whole number from the decimal part. After the decimal point, write 17, because that's the decimal part. And there you have it, 77.17! Ta-da! Now you can go impress all your friends with your amazing math skills.

To write the number 77.17 in decimal format, follow these steps:

1. The whole number part is 77. So write down 77 as the whole number.
2. The decimal part is 0.17. The first digit after the decimal point represents the tenths place. Write down 1 as the digit in the tenths place.
3. The next digit after the tenths place represents the hundredths place. Write down 7 as the digit in the hundredths place.

Putting it all together, the number 77.17 in decimal format uses two decimal places.

To show the number 77.17 using place-value blocks, you would need the following blocks:

- 7 tens blocks (7 × 10 = 70)
- 7 ones blocks
- 1 tenth block (0.1)
- 7 hundredths blocks (0.01 × 7 = 0.07)

Arrange the blocks as follows:

77
- .
1
7

The 7 tens blocks represent the value of 70, the 7 ones blocks represent the value of 7, the 1 tenth block represents the value of 0.1, and the 7 hundredths blocks represent the value of 0.07. Combining them together, you get 77.17.
