Learn how to find what is 9/4 minus 2 in fraction form just in a few minutes. We have covered the easiest method to write 9/4 - 2 as a fraction and decimal.
Summary: 9/4 minus 2
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 9/4 and 2 having identical denominators before starting adding the fractions. Find the LCM of denominators, 4 is the LCM of 4 and 1. Multiply the LCM 4 with all the numerators and denominators of both fractions (9/4 x 4/4) - (2 x 4/4) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 1/4.
The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 2 from 9/4. use any one of the following methods to find the equivalent fraction for 9/4 minus 2.
1. LCM method
2. Cross multiplication method.
9/4-2 using LCM Method:
What is 9/4 minus 2 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/4
Fraction B: 2/1
What to be found?
9/4-2 = ?
Find what's the difference between 9/4 and 2.
step 2 Compare the denominators of fractions 9/4 and 2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/4 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 9/4 and 2:
The LCM of 4 and 1 is 4.
step 4 Write the fractions 9/4 and 2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/4-2
=(9 x 4)/(4 x 4)-(2 x 4)/(1 x 4)
step 5 Simplify the expression to have common denominator:
=9/4-8/4
step 6 Take the common values out and rewrite the above expression like the below:
=1/4 x (9/1-8/1)
=1/4 x (9 - 8)
step 7Simplify the above expression further:
=1/4 x 1
=1/4
9/4-2=1/4
Hence,
9/4 minus 2 equals to 1/4 in fraction.
9/4-2 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/4
Fraction B: 2/1
What to be found?
9/4-2 = ?
Find what's the difference between 9/4 and 2.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 1), find the product of numerator of Fraction B and denominator of Fraction A (2 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:
= (9 x 1) - (2 x 4)/(4 x 1)
step 3 Simplify and rewrite the fraction:
= (9 - 8)/4
9/4-2 = 1/4
Hence,
9/4 minus 2 = 1/4
