Converting Circle Sectors to Numerical Fractions: Visual Analysis

Question

Write the fraction shown in the drawing, in numbers:

00:00 Convert from drawing to simple fraction

00:03 To convert to fraction, what's red will be in numerator and black in denominator

00:07 We can see that the whole is divided into 7 parts

00:17 Therefore in denominator we'll put 7

00:22 Out of all parts, only 3 are colored

00:26 Therefore we'll put 3 in numerator

00:29 And this is the solution to the question

The number of parts in the circle represents the denominator of the fraction, and the number of colored parts represents the numerator.

The circle is divided into 8 parts, 3 parts are colored.

Hence:

$\frac{3}{8}$

$\frac{3}{8}$
