Step 2: Multiply given fraction with reciprocal of given whole number (calculated in step 1)
Step 3: Multiplication of numerators, divided by, multiplication of denominators
Example 1 : Divide
15 4
by 10
Answer = Write fraction and whole number in division expression and we get:
15 4
÷
10
Find the Reciprocal of whole number i.e. 10
Reciprocal of 10
=
1 10
Multiply fraction with the reciprocal of whole number (calculated above) and we get;
=
15 4
x
1 10
Multiplication of numerators, divided by, multiplication of denominators and we get;
=
15 x 1 4 x 10
=
15 40
Example 2 : Divide
53 10
by 5
Answer = Write fraction and whole number in division expression and we get:
53 10
÷ 5
Find the Reciprocal of whole number i.e. 5
Reciprocal of 5
=
1 5
Multiply fraction with the reciprocal of whole number (calculated above) and we get;
53 10
x
1 5
Multiplication of numerators, divided by, multiplication of denominators and we get;
53 x 1 10 x 5
=
53 10
Division of Whole Number by Fraction
Steps of division are:
Step 1: Find reciprocal of given fraction
Step 2: Multiply given whole number with reciprocal of given fraction (calculated in step 1)
Step 3: Multiply whole number with the numerator and keep the denominator same
Example 3 : Solve 2 ÷
3 5
Answer = Find the Reciprocal of fraction and we get
Reciprocal of fraction
3 5
=
5 3
Multiply whole number (i.e. 2) with the reciprocal of fraction (calculated above) and we get
= 2 x
5 3
Multiply whole number with the numerator and keep the denominator same & we get;
=
2 x 5 3
=
10 3
Example 4 : Solve 10 ÷
77 86
Answer = Find the Reciprocal of fraction and we get
Reciprocal of
77 86
=
86 77
Multiply whole number with the reciprocal of fraction (calculated above) and we get
= 10 x
86 77
Multiply whole number with the numerator and keep the denominator same & we get;
=
10 x 86 77
=
860 77
