(0:01) Real-Life Fraction Examples: Visualising fractions with examples like pizza slices helps students see how fractions represent portions of a whole.
(0:25) Fraction Definition in Maths: Fractions represent parts of a whole, using a numerator (top number) and a denominator (bottom number) separated by a horizontal bar.
(1:13) Numerator and Denominator Explained: The numerator indicates the number of parts being considered, while the denominator shows the total number of equal parts the whole is divided into.
(1:58) Calculating Fractions of Quantities: To find a fraction of a quantity, divide it by the denominator, then multiply by the numerator (e.g., $\large \frac{3}{4} $ of 20 cm equals 15 cm).

Introduction to Fractions

1 / 6

Q: In a fraction, what does the denominator tell us?

The total number of parts

How many equal parts the whole is divided into

How many portions are being considered

Feedback: Not quite! The denominator tells us how many equal parts the whole is divided into.

Feedback: Well done! The denominator tells us how many equal parts the whole is divided into.

2 / 6

Q: A rectangle is divided into 10 equal sections. What fraction of the rectangle is yellow?

$Illustrates a fraction using a bar divided into 10 equal sections, with 7 shaded in yellow, representing the fraction 7/10.$

$\frac{7}{12}$

$\frac{10}{7}$

$\frac{7}{10}$

$\frac{3}{10}$

Feedback: Not quite! There are 7 yellow sections out of 10 equal sections, so the fraction is $\frac{7}{10}$.

Feedback: Well done! There are 7 yellow sections out of 10 equal sections, so the fraction is $\frac{7}{10}$.

3 / 6

Q: A team of 8 students shares 5 pizzas equally. What fraction of a pizza does each student get?

$\frac{1}{5}$

$\frac{8}{5}$

$\frac{5}{8}$

Feedback: Not quite! To share 5 pizzas equally among 8 students, each student gets $\frac{5}{8}$ of a pizza.

Feedback: Well done! To share 5 pizzas equally among 8 students, each student gets $\frac{5}{8}$ of a pizza.

4 / 6

Q: If a cake is divided into 12 equal slices and 7 slices are left, what fraction of the cake has been eaten?

$\frac{5}{12}$

$\frac{7}{12}$

$\frac{12}{7}$

Feedback: Not quite! If 7 out of 12 slices are left, then 5 slices have been eaten. The fraction of the cake that has been eaten is $\frac{5}{12}$.

Feedback: Well done! If 7 out of 12 slices are left, then 5 slices have been eaten. The fraction of the cake that has been eaten is $\frac{5}{12}$.

5 / 6

Q: A pool is filled to 3/4 of its capacity, and it holds 60 liters when full. How much water is currently in the pool?

30 liters

50 liters

45 liters

Feedback: Not quite! If the pool is filled to $\frac{3}{4}$ of its capacity and it holds 60 liters when full, then the amount of water is $\frac{3}{4}$ × 60 = 45 liters.

Feedback: Well done! If the pool is filled to $\frac{3}{4}$ of its capacity and it holds 60 liters when full, then the amount of water is $\frac{3}{4}$ × 60 = 45 liters.

6 / 6

Q: A baker has 3/5 of a bag of flour left, which weighs 15 kilograms. What is the total weight of a full bag of flour?

20 kg

25 kg

30 kg

Feedback: Not quite! If $\frac{3}{5}$ of a bag weighs 15 kg, then the total weight of a full bag is 15 ÷ $\frac{3}{5}$ = 15 × $\frac{5}{3}$ = 25 kg.

Feedback: Well done! If $\frac{3}{5}$ of a bag weighs 15 kg, then the total weight of a full bag is 15 ÷ $\frac{3}{5}$ = 15 × $\frac{5}{3}$ = 25 kg.
