Understanding the Idea of a Combined Quantity
A combined quantity is a illustration of a quantity that mixes a complete quantity and a fraction. It’s written as a complete quantity adopted by a fraction, separated by an area. For instance, eighteen and two-tenths can be written as 18 2/10.
Combined numbers are sometimes used to characterize measurements or portions that aren’t complete numbers. As an illustration, a recipe may name for 1 1/2 cups of flour, or a carpenter may measure a bit of wooden to be 3 3/4 inches lengthy.
Changing a Combined Quantity to a Decimal
To transform a combined quantity to a decimal, observe these steps:
- Multiply the entire quantity by the denominator of the fraction.
- Add the numerator of the fraction to the product from step 1.
- Divide the sum from step 2 by the denominator of the fraction.
For instance, to transform 18 2/10 to a decimal, we’d do the next:
- 18 × 10 = 180
- 180 + 2 = 182
- 182 ÷ 10 = 18.2
Subsequently, 18 2/10 is the same as 18.2 in decimal type.
| Combined Quantity | Decimal |

| … | … | … | 1.1111… |
As you possibly can see, the division course of continues indefinitely, with the rest all the time being 1. This means that the decimal illustration of 10/9 is a non-terminating, non-repeating decimal, denoted as 1.1111… or 1.1.
Multiplying the Fraction by 10 to Take away the Denominator
To transform a fraction to a decimal, we have to eradicate the denominator. Within the case of 18 and a couple of/10, the denominator is 10. A technique to do that is by multiplying each the numerator and denominator by the identical quantity, on this case, 10.
Once we multiply the denominator by 10, it shifts the decimal level one place to the proper. To compensate for this, we should additionally multiply the numerator by 10, which is able to successfully take away the denominator and convert the fraction right into a decimal.
So, let’s multiply each the numerator and denominator of 18 and a couple of/10 by 10:
| Numerator | Denominator |
|---|---|
| 18 * 10 = 180 | 2 * 10 = 20 |
Now, our fraction turns into 180/20.
Because the denominator is now 10, we will merely divide the numerator by 10 to get the decimal type:
180 ÷ 20 = 9
Subsequently, 18 and a couple of/10 in decimal type is just 9.
Combining the Complete Quantity and Decimal Parts
After getting transformed the combined quantity to a decimal, the ultimate step is to mix the entire quantity and decimal parts.

To mix the entire quantity and decimal parts, merely place a decimal level between them. The decimal level needs to be positioned instantly after the entire quantity.
For instance, when you have transformed the combined quantity 18 and a couple of/10 to decimal type, you’ll have 18.2.
| Combined Quantity | Decimal Type |
|---|---|
| 18 2/10 | 18.2 |
The decimal 18.2 represents the unique combined quantity 18 and a couple of/10. The entire quantity 18 represents the 18 complete models, and the decimal portion .2 represents the two/10 of a unit.
Combining the entire quantity and decimal parts is an easy course of, however it is very important place the decimal level appropriately. If the decimal level is positioned incorrectly, the worth of the decimal shall be completely different from the worth of the unique combined quantity.
Simplifying the Ensuing Decimal Fraction
The ensuing decimal fraction 18.2 might be simplified additional by eradicating any trailing zeros.
To do that, we will carry out the next steps:
1. Discover the final non-zero digit within the decimal fraction. On this case, it’s 2.
2. Transfer the decimal level to the left till the final non-zero digit is the rightmost digit.
3. Add sufficient zeros to the proper of the decimal level to make the quantity a complete quantity.
Making use of these steps to 18.2, we get:
18.2 → 182/10 → 1820/100
Subsequently, 18.2 might be simplified to 18.20 or 18.200.
