**Modeling Decimals (Area and Grid Models)**

- Understand that a
**decimal**is any number written in the base-10 system. - Represent
**decimals**using area**models**. - State the fraction (tenths or hundredths) that is equivalent to a given
**decimal**. - Compare the values of
**decimals**(tenths or hundredths) using area**models**and/or a number line.

Besides, how do you model a decimal using a fraction?

**Answer**

- Answer.

- You model a decimal using a fraction : multiply the denominator and numerator by 10 for every number after the decimal point after we change the decimal in fractions with the denominator 1. Further explanation. Fraction numbers are known as numerators and denominators.

Secondly, why is a decimal times a decimal smaller? When multiplying a number by a **decimal** less than one, the product will be **smaller** than the number being multiplied. This is because we are finding a fractional amount of a quantity. For example, 0.1 x 0.8 = 0.08, because the question is asking us to find one tenth of eight tenths.

Likewise, how do we multiply 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.

How do we divide decimals?

To **divide decimal** numbers: Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's.
