In this section, you will learn, how to write a mixed number as improper fraction.
The picture shown below illustrates how to write a mixed number as an improper fraction.
Example 1 :
Write the following mixed number as improper fraction.
Solution :
We have to do the following steps to write the given mixed number as improper fraction.
Step 1 :
Multiply the denominator 3 by the whole number 91.
Thus, we get 273
Step 2 :
Add this 273 to the numerator 2.
Thus, we get 275.
Step 3 :
Now, form a fraction with this 275 as numerator and 3 (denominator in the given mixed number) as denominator.
Therefore, the required improper fraction is 275/3.
Example 2 :
Write the following mixed number as improper fraction.
Solution :
We have to do the following steps to write the given mixed number as improper fraction.
Step 1 :
Multiply the denominator 7 by the whole number 22.
Thus, we get 154
Step 2 :
Add this 154 to the numerator 1.
Thus, we get 155.
Step 3 :
Now, form a fraction with this 155 as numerator and 7 (denominator in the given mixed number) as denominator.
Therefore, the required improper fraction is 155/7.
Example 3 :
Write the following mixed number as improper fraction.
Solution :
We have to do the following steps to write the given mixed number as improper fraction.
Step 1 :
Multiply the denominator 13 by the whole number 60.
Thus, we get 780
Step 2 :
Add this 780 to the numerator 2.
Thus, we get 782.
Step 3 :
Now, form a fraction with this 782 as numerator and 13 (denominator in the given mixed number) as denominator.
Therefore, the required improper fraction is 782/13.
Example 4 :
Write the following mixed number as improper fraction.
Solution :
We have to do the following steps to write the given mixed number as improper fraction.
Step 1 :
Multiply the denominator 8 by the whole number 9.
Thus, we get 72
Step 2 :
Add this 72 to the numerator 3.
Thus, we get 75.
Step 3 :
Now, form a fraction with this 75 as numerator and 8 (denominator in the given mixed number) as denominator.
Therefore, the required improper fraction is 75/8.
Example 5 :
Write the following mixed number as improper fraction.
Solution :
We have to do the following steps to write the given mixed number as improper fraction.
Step 1 :
Multiply the denominator 15 by the whole number 11.
Thus, we get 165
Step 2 :
Add this 165 to the numerator 13.
Thus, we get 178.
Step 3 :
Now, form a fraction with this 178 as numerator and 15 (denominator in the given mixed number) as denominator.
Therefore, the required improper fraction is 178/15.
