Learn how to find what is 13/9 minus 4 in fraction form just in a few minutes. We have covered the easiest method to write 13/9 - 4 as a fraction and decimal.
Summary: 13/9 minus 4 = -23/9
Since both fractions have unequal denominators, 13/9 minus 4 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 13/9 and fraction 4 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 9 and 1. 9 is the LCM of 9 and 1. Multiplying the LCM 9 with the numerators and denominators of both fractions (13/9 x 9/9) - (4 x 9/9), and simplify further in order to have the common denominator. So the equivalent fraction for 13/9 is 13/9 and for 4 is 36/9. By simplifying this fraction subtraction 13/9 - 36/9, it becomes -23/9.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 4 from 13/9. use any one of the following methods to find the equivalent fraction for 13/9 minus 4.
1. LCM method
2. Cross multiplication method.
(13/9) - (4) using LCM Method:
What is 13/9 minus 4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/9
Fraction B: 4/1
What to be found?
(13/9) - (4) = ?
Find what's the difference between 13/9 and 4.
step 2 Compare the denominators of fractions 13/9 and 4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/9 and 4 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 13/9 and 4:
The LCM of 9 and 1 is 9.
step 4 Write the fractions 13/9 and 4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/9 - 4
= [(13 x 9)/(9 x 9)] - [(4 x 9)/(1 x 9)]
step 5 Simplify the expression to have common denominator:
= 13/9 - 36/9
step 6 Take the common values out and rewrite the above expression like the below:
= 1/9 x (13/1 - 36/1)
= 1/9 x (13 - 36)
step 7Simplify the above expression further:
= 1/9 x -23
= -23/9
13/9 - 4 = -23/9
Hence,
13/9 minus 4 as a fraction is -23/9.
13/9 - 4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/9
Fraction B: 4/1
What to be found?
(13/9)-(4) = ?
Find what's the difference between 13/9 and 4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (13 x 1), find the product of numerator of Fraction B and denominator of Fraction A (4 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 1) and rewrite the equation as like the below:
= (13 x 1) - (4 x 9)/(9 x 1)
step 3 Simplify and rewrite the fraction:
= (13 - 36)/9
13/9 - 4 = -23/9
Hence,
13/9 minus 4 in fraction is -23/9
