What must you do if there is a decimal in the divisor?

DIVIDING DECIMALS

When the divisor is a decimal, what must we do?
1)	Multiply the divisor by 10, or 100, or 1000, etc., according to the number of decimal digits, so that it becomes a whole number.
2)	Multiply the dividend by the same power of 10.

When dividing decimals What must you do if there is a decimal in the divisor * make the divisor a whole number by multiplying the divisor and dividend by the same factor of 10 make the dividend a whole number by multiplying the divisor and dividend by the same factor of 10 make the divisor a whole?

In this step you convert the divisor from a decimal number to a whole number. 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 do you do if you have a decimal in the dividend and divisor?

Summary: When dividing by a decimal divisor, we use the following procedure:

Multiply the divisor by a power of 10 to make it a whole number.
Multiply the dividend by the same power of 10. Place the decimal point in the quotient.
Divide the dividend by the whole-number divisor to find the quotient.

How do you divide a decimal by a decimal?

To divide a decimal by another decimal: Move the decimal point in the divisor to the right until it is a whole number. Move the decimal point in the dividend to the right by the same number of places as the decimal point was moved to make the divisor a whole number. Then divide the new dividend by the new divisor.

How do you divide a decimal by 1000?

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 solve decimals?

Multiply the numbers just as if they were whole numbers.

Line up the numbers on the right – do not align the decimal points.
Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers.
Add the products.

What are the four rules of decimals?

You should become efficient in using the four basic operations involving decimals—addition, subtraction, multiplication, and division.

How do you calculate decimals without a calculator?

It’ll be really easy! Ignore the decimal points and multiply as usual… Count how many total digits are on the right side of the decimal points in the guys you are multiplying… Place the decimal point in your answer so there are this many digits to the right.

How do you explain decimal places?

Commonly speaking we talk about decimals when numbers include a decimal point to represent a whole number plus a fraction of a whole number (tenths, hundredths, etc.). A decimal point is a point or dot used to separate the whole part of a number from the fractional part of a number.

How do I find 15 of a number?

15% is 10% + 5% (or 0.15 = 0.1 + 0.05, dividing each percent by 100). Thinking about it this way is useful for two reasons. First, it’s easy to multiply any number by 0.1; just move the decimal point left one digit. For example, 75.00 x 0.1 = 7.50, or 346.43 x 0.1 = 34.64 (close enough).
