Math Lesson 2:
Fractions and Decimals

Introduction to Fractions and Decimals

In this lesson, we'll learn about fractions and decimal numbers. These concepts are important for representing parts of a whole and for precise measurements.

Fractions

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, in 3/4, 3 is the numerator and 4 is the denominator.

Exercise: Identifying Fractions

Enter the numerator and denominator of the fraction 5/8:

Decimals

Decimals are another way to represent parts of a whole. They use a decimal point to show tenths, hundredths, and so on. For example, 0.75 is equivalent to 75/100 or 3/4.

Exercise: Converting Fractions to Decimals

Convert the fraction 1/4 to a decimal:

Comparing Fractions and Decimals

We can compare fractions and decimals to see which is greater. For example, 1/2 is equal to 0.5, and both are less than 3/4 or 0.75.

Exercise: Comparing Numbers

Which is greater: 2/3 or 0.6?

Adding Fractions and Decimals

We can add fractions with the same denominator, and we can add decimals by lining up the decimal points.

Exercise: Addition

Add 1/4 and 0.5:
