3 - 3/6 as a fraction

Learn how to find what is 3 minus 3/6 in fraction form just in a few minutes. We have covered the easiest method to write 3 - 3/6 as a fraction and decimal.

Summary: 3 minus 3/6 = 5/2
Since both fractions have unequal denominators, 3 minus 3/6 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 3 and fraction 3/6 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 6. 6 is the LCM of 1 and 6. Multiplying the LCM 6 with the numerators and denominators of both fractions (3 x 6/6) - (3/6 x 6/6), and simplify further in order to have the common denominator. So the equivalent fraction for 3 is 18/6 and for 3/6 is 3/6. By simplifying this fraction subtraction 18/6 - 3/6, it becomes 15/6.

CALCULATION: 3 - 3/6 as a fraction
3 - 3/6 = (?)
3/1 - 3/6 = [(3 x 6) - (3 x 1)]/(1 x 6)
= (18 - 3)/6
= 15/6
= (3 x 5)/(3 x 2)
= 5/2
3 - 3/6 = 5/2
3 minus 3/6 as a fraction is 5/2.

where
3 is a whole number as a minuend,
3/6 is a proper fraction as a subtrahend,
5/2 is the difference between 3 and 3/6.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/6 from 3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3 minus 3/6.
1. LCM method
2. Cross multiplication method.

(3) - (3/6) using LCM Method:
What is 3 minus 3/6 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/1
Fraction B: 3/6

What to be found?
(3) - (3/6) = ?
Find what's the difference between 3 and 3/6.

step 2 Compare the denominators of fractions 3 and 3/6 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3 and 3/6 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 3 and 3/6:
The LCM of 1 and 6 is 6.

step 4 Write the fractions 3 and 3/6 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 3 - 3/6
= [(3 x 6)/(1 x 6)] - [(3 x 6)/(6 x 6)]

step 5 Simplify the expression to have common denominator:
= 18/6 - 3/6

step 6 Take the common values out and rewrite the above expression like the below:
= 1/6 x (18/1 - 3/1)
= 1/6 x (18 - 3)

step 7Simplify the above expression further:
= 1/6 x 15
= 15/6
= 5/2
3 - 3/6 = 5/2

Hence,
3 minus 3/6 as a fraction is 5/2.

3 - 3/6 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/1
Fraction B: 3/6

What to be found?
(3)-(3/6) = ?
Find what's the difference between 3 and 3/6.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 6), find the product of numerator of Fraction B and denominator of Fraction A (3 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 6) and rewrite the equation as like the below:
= (3 x 6) - (3 x 1)/(1 x 6)

step 3 Simplify and rewrite the fraction:
= (18 - 3)/6
= 15/6
= 5/2
3 - 3/6 = 5/2

Hence,
3 minus 3/6 in fraction is 5/2
