Learn how to find what is 7/8 minus 11 in fraction form just in a few minutes. We have covered the easiest method to write 7/8 - 11 as a fraction and decimal.
Summary: 7/8 minus 11 = -81/8
Since both fractions have unequal denominators, 7/8 minus 11 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/8 and fraction 11 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 8 and 1. 8 is the LCM of 8 and 1. Multiplying the LCM 8 with the numerators and denominators of both fractions (7/8 x 8/8) - (11 x 8/8), and simplify further in order to have the common denominator. So the equivalent fraction for 7/8 is 7/8 and for 11 is 88/8. By simplifying this fraction subtraction 7/8 - 88/8, it becomes -81/8.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 11 from 7/8. use any one of the following methods to find the equivalent fraction for 7/8 minus 11.
1. LCM method
2. Cross multiplication method.
(7/8) - (11) using LCM Method:
What is 7/8 minus 11 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 11/1
What to be found?
(7/8) - (11) = ?
Find what's the difference between 7/8 and 11.
step 2 Compare the denominators of fractions 7/8 and 11 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/8 and 11 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 11:
The LCM of 8 and 1 is 8.
step 4 Write the fractions 7/8 and 11 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/8 - 11
= [(7 x 8)/(8 x 8)] - [(11 x 8)/(1 x 8)]
step 5 Simplify the expression to have common denominator:
= 7/8 - 88/8
step 6 Take the common values out and rewrite the above expression like the below:
= 1/8 x (7/1 - 88/1)
= 1/8 x (7 - 88)
step 7Simplify the above expression further:
= 1/8 x -81
= -81/8
7/8 - 11 = -81/8
Hence,
7/8 minus 11 as a fraction is -81/8.
7/8 - 11 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/8
Fraction B: 11/1
What to be found?
(7/8)-(11) = ?
Find what's the difference between 7/8 and 11.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 1), find the product of numerator of Fraction B and denominator of Fraction A (11 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:
= (7 x 1) - (11 x 8)/(8 x 1)
step 3 Simplify and rewrite the fraction:
= (7 - 88)/8
7/8 - 11 = -81/8
Hence,
7/8 minus 11 in fraction is -81/8
