Learn how to find what is 5/8 minus 1 in fraction form just in a few minutes. We have covered the easiest method to write 5/8 - 1 as a fraction and decimal.
Summary: 5/8 minus 1
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 5/8 and 1 having identical denominators before starting adding the fractions. Find the LCM of denominators, 8 is the LCM of 8 and 1. Multiply the LCM 8 with all the numerators and denominators of both fractions (5/8 x 8/8) - (1 x 8/8) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes -3/8.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 1 from 5/8. use any one of the following methods to find the equivalent fraction for 5/8 minus 1.
1. LCM method
2. Cross multiplication method.
5/8-1 using LCM Method:
What is 5/8 minus 1 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/8
Fraction B: 1/1
What to be found?
5/8-1 = ?
Find what's the difference between 5/8 and 1.
step 2 Compare the denominators of fractions 5/8 and 1 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/8 and 1 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 5/8 and 1:
The LCM of 8 and 1 is 8.
step 4 Write the fractions 5/8 and 1 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=5/8-1
=(5 x 8)/(8 x 8)-(1 x 8)/(1 x 8)
step 5 Simplify the expression to have common denominator:
=5/8-8/8
step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (5/1-8/1)
=1/8 x (5 - 8)
step 7Simplify the above expression further:
=1/8 x -3
=-3/8
5/8-1=-3/8
Hence,
5/8 minus 1 equals to -3/8 in fraction.
5/8-1 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/8
Fraction B: 1/1
What to be found?
5/8-1 = ?
Find what's the difference between 5/8 and 1.
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 (1 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 1) and rewrite the equation as like the below:
= (5 x 1) - (1 x 8)/(8 x 1)
step 3 Simplify and rewrite the fraction:
= (5 - 8)/8
5/8-1 = -3/8
Hence,
5/8 minus 1 = -3/8
