How do you divide a whole number and a fraction?

To divide whole numbers by a fraction, we use the same procedure we use when we divide a fraction by a fraction: we invert (flip) the denominator (bottom number) and multiply. To do this for whole numbers, we remember that a whole number can be written as a fraction by making the denominator a 1. So 3 is the same as 3/1, 4 is 4/1, and so on.

What are the different ways of multiplication?

The Different Ways to Multiply. This lesson will cover four different ways to multiply numbers: addition, memorizing the grid method, long multiplication, and drawing lines. Learning about each of them will help you decide which method works best for you.

How do you multiply two numbers?

Here’s how to multiply two numbers that are in scientific notation: 1. Multiply the two decimal parts of the numbers. 2. Multiply the two exponential parts by adding their exponents. 3. Write the answer as the product of the numbers you found in Steps 1 and 2.

How do you calculate integers?

Count the number of integers in your list. In our example, there are five integers. Divide the sum of the integers by the number of integers. In our example, the sum of the integers is 24, and there are five integers total, so this is the formula: 24 / 5 = 4.8.

How do you convert a decimal into a whole number?

To turn a decimal into a whole number, you can multiply it by how many decimal places there are, thereby moving every digit over the decimal point. Or you can round it to the nearest ones digit, if you do not care about preserving the entire number.

What is the number that multiplies a variable?

A Coefficient is a number used to multiply a variable ( 4x means 4 times x, so 4 is a coefficient) Variables on their own (without a number next to them) actually have a coefficient of 1 ( x is really 1x)
