Question

A cup is quarter full of water. part of the cup still needs to be filled by water to make it full

• A. $\frac{1}{4}$
• B. $\frac{3}{4}$
• C. $\frac{1}{3}$
• D. $\frac{1}{2}$

Answer 1

The correct option is B $\frac{3}{4}$

We know that, fractions are a part of whole.

Part of cup filled + part of cup not filled = 1 (Whole part of the cup is 1)

Given, part of cup filled with water = 1 quarter
Four quarters represent one whole.

Remaining part of the cup which is not filled by water

= Whole part of the cup - part of the cup filled with water

= 4 quarters - 1 quarter

= 3 quarters

Hence, the part of the cup that still needs to be filled is three - quarters
= $\frac{3}{4}$.30038
