Question

What part of the circle is Blue and what part is grey?

A) Blue Part ${\displaystyle \frac{1}{4}}$, Grey Part ${\displaystyle \frac{3}{4}}$
B) Blue Part ${\displaystyle \frac{1}{2}}$, Grey Part ${\displaystyle \frac{1}{2}}$
C) Blue Part ${\displaystyle \frac{1}{4}}$, Grey Part ${\displaystyle \frac{1}{2}}$
D) Blue Part ${\displaystyle \frac{1}{2}}$, Grey Part ${\displaystyle \frac{3}{4}}$

Answer 1

Hint: As we can see that the circle is divided into 4 parts which means 4 parts make a whole of the circle. So firstly we will check how many parts of the circle are in Blue color and how many parts of the circle are in Grey color. Then we will divide each part obtained by the total number of parts of a circle and get our desired answer.

Complete step by step answer:
It is given to us that a circle is divided into 4 parts.
Next we observe that only one part of the circle is in Blue color and the rest 3 parts are in Grey color.
Blue Part $=1$
Grey Part $=3$
 So to find out what part of the circle is Blue and what part is grey we will use the fraction method.
Blue Part = Number of Blue part/ Total number of part
Blue Part $={\displaystyle \frac{1}{4}}$
Grey Part = Number of Grey Part/ Total number of part
Grey Part $={\displaystyle \frac{3}{4}}$
So we get that Blue Part $={\displaystyle \frac{1}{4}}$ and Grey Part $={\displaystyle \frac{3}{4}}$

So, the correct answer is “Option A”.

Note:
 Fractions are defined as the parts of a whole. The whole can be anything, a number or any specific value or a thing. The fraction has two parts: the upper part is known as the numerator and the lower part is known as the denominator. The numerator is that part of the value whose fraction is to be determined and the denominator is the total parts of the whole.
