Learn how to find what is 5/7 minus 2 in fraction form just in a few minutes. We have covered the easiest method to write 5/7 - 2 as a fraction and decimal.
Summary: 5/7 minus 2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 5/7 and 2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 7 is the LCM of 7 and 1. Multiply the LCM 7 with all the numerators and denominators of both fractions (5/7 x 7/7) - (2 x 7/7) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -9/7.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 2 from 5/7. use any one of the following methods to find the equivalent fraction for 5/7 minus 2.
1. LCM method
2. Cross multiplication method.
5/7-2 using LCM Method:
What is 5/7 minus 2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 2/1
What to be found?
5/7-2 = ?
Find what's the difference between 5/7 and 2.
step 2 Compare the denominators of fractions 5/7 and 2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 and 2 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 5/7 and 2:
The LCM of 7 and 1 is 7.
step 4 Write the fractions 5/7 and 2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/7-2
=(5 x 7)/(7 x 7)-(2 x 7)/(1 x 7)
step 5 Simplify the expression to have common denominator:
=5/7-14/7
step 6 Take the common values out and rewrite the above expression like the below:
=1/7 x (5/1-14/1)
=1/7 x (5 - 14)
step 7Simplify the above expression further:
=1/7 x -9
=-9/7
5/7-2=-9/7
Hence,
5/7 minus 2 equals to -9/7 in fraction.
5/7-2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 2/1
What to be found?
5/7-2 = ?
Find what's the difference between 5/7 and 2.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 1), find the product of numerator of Fraction B and denominator of Fraction A (2 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 1) and rewrite the equation as like the below:
= (5 x 1) - (2 x 7)/(7 x 1)
step 3 Simplify and rewrite the fraction:
= (5 - 14)/7
5/7-2 = -9/7
Hence,
5/7 minus 2 = -9/7
