How do you multiply and divide decimals by powers of 10?

When you multiply a decimal by a power of 10, simply move the decimal place to the right as many places as there are 0s in the power of 10. When you divide a decimal by a power of 10, simply move the decimal place to the left as many places as there are 0s in the power of 10.

How do you explain dividing by 10?

Dividing by 1, 10 or 100When you divide by 1 the answer stays the same. 21 ÷ 1 = 21.When you divide by 10, move all the digits one place to the right. 210 ÷ 10 = 21.When you divide by 100, move all the digits two places to the right. 2100 ÷ 100 = 21.

How do you divide a decimal by 100?

To divide a whole or a decimal number by 100, move the decimal point two places to the left. Note that although a whole number does not have a decimal point, we can always add it at the end of the number. (For example, 35 and 35.

What are the five rules of exponents?

Exponent rulesProduct of powers rule. When multiplying two bases of the same value, keep the bases the same and then add the exponents together to get the solution. … Quotient of powers rule. … Power of a power rule. … Power of a product rule. … Power of a quotient rule. … Zero power rule. … Negative exponent rule.

What happens to powers when you divide?

If you are dividing, we subtract exponents. But, subtracting a negative will change it to a positive.

How do you move the decimal point in division?

You do this by moving the decimal point to the right in the divisor until there are no more numbers other than zero to the right of the decimal point. Then you move the decimal point to the right the same number of places in the dividend.

What pattern describes how the decimal point moves when you divide a decimal by any power of 10?

We know that the decimal point goes to the right of the ones place. So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. For each power of ten, you move one place to the left.

How do you divide powers?

To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.

Which is the same as dividing a number by 1 000?

There is a similar shortcut for multiplying decimal numbers by numbers such as 10, 100, and 1000: Move the decimal point to the right as many places as there are zeros in the factor. Move the decimal point one step to the right (10 has one zero). Move the decimal point two steps to the right (100 has two zeros).

How do you explain dividing by 100?

To divide by 100, move each digit two place value columns to the right. If the number ends in two ‘0’ digits in the tens and units columns, dividing by 100 has the same effect as removing these digits. To divide by 100, move all digits two place value columns to the right.
