Question

Farookh cuts an apple into 12 equal pieces and gives 5 pieces to his best friend. If he eats 4 pieces, what part of the apple is left with Farookh?

• A. 0.20
• B. 0.25
• C. 0.15
• D. 0.30

Answer 1

The correct option is B

0.25

Farookh eats 4 pieces of the apple and gives 5 pieces to his friend.
$\therefore \text{Total pieces of apple eaten}=\frac{5}{12}+\frac{4}{12}=\frac{9}{12}\text{Remaining pieces}=1-\frac{9}{12}=\frac{12-9}{12}=\frac{3}{12}\left(\text{Reducing by common factor}\right)=\frac{3÷3}{12÷3}=\frac{1}{4}\text{Multiply by 25 (both numerator and denominator})=\frac{1\times 25}{4\times 25}=\frac{25}{100}=0.25$
