One-Tenth
One-tenth is the foundation of decimal and metric understanding in Grade 8 math (Yoshiwara Core Math). One-tenth (1/10 = 0.1) represents dividing a quantity into 10 equal parts and taking one. On a number line, 0.1 is the first mark in the 0-to-1 interval divided into 10 parts. In place value, the tenths digit is the first decimal place (e.g., 3.7 means 3 ones and 7 tenths). Finding 1/10 requires dividing by 10. The metric prefix 'deci-' means one-tenth (1 decimeter = 1/10 meter). Mastering one-tenth enables fluency with decimals, percentages, and the metric system.
Key Concepts
Property Tenths are important fractions because they are the foundation of our decimal number system. We can represent one tenth in several ways:.
$\frac{1}{10}$ One out of ten $0.1$ The first place after the decimal point is the tenths place. $0.10$ Ten hundredths is the same as one tenth: $\frac{10}{100}=\frac{1}{10}$.
To find $\frac{1}{10}$ of a number, we divide by 10.
Common Questions

One-tenth = 1/10 = 0.1.
How do you find one-tenth of a number?
Divide by 10. 1/10 of 250 = 25.
Where is one-tenth on a number line?
Divide 0 to 1 into 10 equal parts. One-tenth is the first mark at 0.1.
What is the tenths place in a decimal?
The first digit after the decimal point. In 4.7, the 7 is the tenths digit meaning 7 × 0.1.
How does one-tenth relate to 'deci-'?
'Deci-' means one-tenth. A decimeter = 1/10 of a meter; a deciliter = 1/10 of a liter.
