How to find 1/4-3 as a fraction?
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 3 from 1/4. use any one of the following methods to find the equivalent fraction for 1/4 minus 3.
1. LCM method
2. Cross multiplication method.
1/4-3 using LCM Method:
What is 1/4 minus 3 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/4
Fraction B: 3/1
What to be found?
1/4-3 = ?
Find what's the difference between 1/4 and 3.
step 2 Compare the denominators of fractions 1/4 and 3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/4 and 3 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 1/4 and 3:
The LCM of 4 and 1 is 4.
step 4 Write the fractions 1/4 and 3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/4-3
=(1 x 4)/(4 x 4)-(3 x 4)/(1 x 4)
step 5 Simplify the expression to have common denominator:
=1/4-12/4
step 6 Take the common values out and rewrite the above expression like the below:
=1/4 x (1/1-12/1)
=1/4 x (1 - 12)
step 7Simplify the above expression further:
=1/4 x -11
=-11/4
1/4-3=-11/4
Hence,
1/4 minus 3 equals to -11/4 in fraction.
1/4-3 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/4
Fraction B: 3/1
What to be found?
1/4-3 = ?
Find what's the difference between 1/4 and 3.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 1), find the product of numerator of Fraction B and denominator of Fraction A (3 x 4), and find the product of both denominators of Fraction A and Fraction B (4 x 1) and rewrite the equation as like the below:
= (1 x 1) - (3 x 4)/(4 x 1)
step 3 Simplify and rewrite the fraction:
= (1 - 12)/4
1/4-3 = -11/4
Hence,
1/4 minus 3 = -11/4
