7 - 6 (1- 7n) = 127
7 - 6 - 42n = 127
1 - 42n = 127
subtract 1 from both sides
- 42n = 126
divide both sides by -42
n = 3
The value of the mixed number is A = 27/10
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number be represented as A
Now , the equation will be
A = 2 7/10 be equation (1)
On converting the mixed number to an improper fraction , we get
Multiply the whole number by the denominator and add the numerator to it to get the new numerator of the improper fraction
So , A = [ ( 2 x 10 ) + 7 ] / 10
On simplifying the equation , we get
A = 27/10
Hence , the mixed number to improper fraction is A = 27/10
