Learn how to find what is 7/8 minus 1/4 in fraction form just in a few minutes. We have covered the easiest method to write 7/8 - 1/4 as a fraction and decimal.
Summary: 7/8 minus 1/4
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 7/8 and 1/4 having identical denominators before starting adding the fractions. Find the LCM of denominators, 8 is the LCM of 8 and 4. Multiply the LCM 8 with all the numerators and denominators of both fractions (7/8 x 8/8) - (1/4 x 8/8) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 5/8.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/4 from 7/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/8 minus 1/4.
1. LCM method
2. Cross multiplication method.
7/8-1/4 using LCM Method:
What is 7/8 minus 1/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 1/4
What to be found?
7/8-1/4 = ?
Find what's the difference between 7/8 and 1/4.
step 2 Compare the denominators of fractions 7/8 and 1/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/8 and 1/4 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 7/8 and 1/4:
The LCM of 8 and 4 is 8.
step 4 Write the fractions 7/8 and 1/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/8-1/4
=(7 x 8)/(8 x 8)-(1 x 8)/(4 x 8)
step 5 Simplify the expression to have common denominator:
=7/8-2/8
step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (7/1-2/1)
=1/8 x (7 - 2)
step 7Simplify the above expression further:
=1/8 x 5
=5/8
7/8-1/4=5/8
Hence,
7/8 minus 1/4 equals to 5/8 in fraction.
7/8-1/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 1/4
What to be found?
7/8-1/4 = ?
Find what's the difference between 7/8 and 1/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), 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 4) and rewrite the equation as like the below:
= (7 x 4) - (1 x 8)/(8 x 4)
step 3 Simplify and rewrite the fraction:
= (28 - 8)/32
= 20/32
= 5/8
7/8-1/4 = 5/8
Hence,
7/8 minus 1/4 = 5/8
