Solution finding the Subtraction of Fraction 39/21 from Whole Number 3
The given input are 3 and 39/21
3 can be written as 3/1 in fraction format
The given fractions are 3/1 and 39/21
Firstly the L.C.M should be done for the denominators of the two fractions 3/1 and 39/21
3/1 - 39/21
The LCM of 1 and 21 (denominators of the fractions) is 21
Given numbers has no common factors except 1. So, there LCM is their product i.e 21
= 3 x 21 - 39 x 1/21
= 63 - 39/21
= 24/21
= 8/7
Result: 8/7
In order to get the Mixed Number,we need to divide 8 ÷ 7 to get the Quotient and Remainder
8 divided by 7 using long division
The given Divisor = 7 and Dividend = 8
| 1 | |
| 7 | 8 |
| 7 | |
| 1 |
The Quotient is 1 and the Remainder is 1
We get the Quotient = 1 and Remainder = 1
∵ The Mixed-Fraction can be written as QuotientRemainder/Denominator
Result: 1 1/7
