To calculate a ratio, divide two quantities and simplify the result if needed:

• Example: If there are 8 apples and 6 oranges, the ratio is $8:6$ , which simplifies to $4:3$ .

7. How to Calculate Simple Interest in Maths?

Simple interest is calculated using the formula:

• Formula: $$I = P \times r \times t$$  where $P$ is the principal, $r$ is the rate of interest, and $t$ is time.

8. How to Calculate Simple Interest Maths?

The same formula applies:

• Formula: $$I = P \times r \times t$$ 

9. How to Calculate VAT in Maths?

To calculate VAT (Value Added Tax):

• Formula: $$\text{VAT} = \text{Price} \times \frac{\text{VAT rate}}{100}$$
• Example: For a product costing $100 with 20% VAT:
  $\text{VAT} = 100 \times \frac{20}{100} = 20$ .

10. How to Cheat on a Math Test?

Cheating is not advisable. Instead, focus on learning concepts, practicing problems, and preparing adequately. If you’re struggling, seek help from a teacher or tutor.

16. How to Describe a Transformation in Maths?

A transformation involves changing the position, size, or orientation of a figure:

• Translation: Moving the shape without rotating or flipping.
• Rotation: Turning the shape about a point.
• Reflection: Flipping the shape over a line.
• Dilation: Enlarging or reducing the shape.

17. How to Divide Decimals Math Antics?

• Move the decimal point of the divisor to make it a whole number.
• Move the decimal point of the dividend by the same number of places.
• Divide as with whole numbers and place the decimal in the result.

18. How to Divide Fractions Math Antics?

To divide fractions:

• Flip the second fraction (find the reciprocal).
• Multiply the first fraction by the reciprocal of the second.
• Simplify the result if possible.
• Example: $\frac{3}{4} \div \frac{2}{5} = \frac{3}{4} \times \frac{5}{2} = \frac{15}{8}$.

19. How to Divide in Math?

Division is the process of finding how many times one number fits into another:

• Formula: $$\text{Quotient} = \frac{\text{Dividend}}{\text{Divisor}}$$
