By shifting the digits 1 the same number of columns as zeros in the multiplier (eg × 100 has 2 zeros, so shift 2 columns) to the left.
On paper this is much easier to do by considering the effect on the decimal point, which is to move it the same number of digits as zero in the multiplier to the right. (If you run out of digits, remember that an empty place value column is the same as it containing a zero, so you can then add extra zeros until the decimal point has moved enough places.)

How can place values be used to divide by 10s 100s 1000s?
Move the decimal points to the left. The number of places to the left is the number of 0s in the denominator.
How do you group 7561 using 1 ten for 10 ones?
7 lots of 1000s 5 lots of 100s 6 lots of 10s and 1 lot of 1.
How do desimals work?
Decimals work on the principle that each digit is 10 times its predecessor, thus the first digit from the right is the unit, the second is 10s, the third 100s, the fourth 1,000s and so on.
How many hundreds are in a 100000?
The trick is just remove the number of zeros in what you are comparing to.How many 10s remove 1How many 100s remove 2How many 1000s remove 3So remove 2 zeros from 100000 and get 1000
Why are there so many caves in the limestone rock?
It is all thanks to the rock's solubitlity in water, but cave development in any give limestone region is also controlled by the specific geology, hydrology, geomorphology and continued precipitation over 10s or 100s of 1000s of years.

List the features of Pascaline?
The Pascaline was designed and worked by the French mathematician-rationalist Blaise Pascal somewhere in the range of 1642 and 1644. It could only do addition and subtraction by manipulating its dials to enter numbers. The Pascaline was equipped for numerical activities, for example, adding, deducting, and conveying 10s, 100s, and 1000s.
How many positive 3-digit integers can be formed that the 100s digit is equal to the sum of the 10s and 1s digit?

How do you write two hundred four thousand and six tenths?
The decimal places go like: 1000s 100s 10s 1s . 10ths 100ths 1000ths So 7 in the 10ths place, and 6 in the thousands place: 6000.700 If you meant 'six thousandths' instead of thousands, then put the 6 in the 1000ths place like: 0.706
Does the ice caps on the Earth melt naturally?
Yes - and re-form - but over geological time measured in 1000s or 10s of 1000s of years. (The last glacial retreat of the present Ice Age is reckoned to have started about 12000 years ago.)
