To determine

Write the shaded region in fraction and if the fraction is improper write it as mixed fraction.

Answer to Problem 1IR

  $\frac{3}{7}$

Explanation of Solution

Given:

Shaded area

  

Concept Used:

A fraction of shaded part is $\frac{\left(\begin{array}{l}\text{number of }\\ \text{shaded parts}\end{array}\right)}{\left(\begin{array}{l}\text{number of }\\ \text{total parts}\end{array}\right)}$ .

Calculation:

As in the given figure 3 of 7 parts are shaded, thus fraction of shaded part will be known by the formula $\frac{\left(\begin{array}{l}\text{number of }\\ \text{shaded parts}\end{array}\right)}{\left(\begin{array}{l}\text{number of }\\ \text{total parts}\end{array}\right)}$ .

Thus, fraction of shaded part is $\frac{\text{3}}{\text{7}}$ this is a proper fraction.
