2 - 3/10 as a fraction

Learn how to find what is 2 minus 3/10 in fraction form just in a few minutes. We have covered the easiest method to write 2 - 3/10 as a fraction and decimal.

Summary: 2 minus 3/10 = 17/10
Since both fractions have unequal denominators, 2 minus 3/10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2 and fraction 3/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 10. 10 is the LCM of 1 and 10. Multiplying the LCM 10 with the numerators and denominators of both fractions (2 x 10/10) - (3/10 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 2 is 20/10 and for 3/10 is 3/10. By simplifying this fraction subtraction 20/10 - 3/10, it becomes 17/10.

CALCULATION: 2 - 3/10 as a fraction
2 - 3/10 = (?)
2/1 - 3/10 = [(2 x 10) - (3 x 1)]/(1 x 10)
= (20 - 3)/10
= 17/10
2 - 3/10 = 17/10
2 minus 3/10 as a fraction is 17/10.

where
2 is a whole number as a minuend,
3/10 is a proper fraction as a subtrahend,
17/10 is the difference between 2 and 3/10.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/10 from 2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2 minus 3/10.
1. LCM method
2. Cross multiplication method.

(2) - (3/10) using LCM Method:
What is 2 minus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/1
Fraction B: 3/10

What to be found?
(2) - (3/10) = ?
Find what's the difference between 2 and 3/10.

step 2 Compare the denominators of fractions 2 and 3/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2 and 3/10 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 2 and 3/10:
The LCM of 1 and 10 is 10.

step 4 Write the fractions 2 and 3/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2 - 3/10
= [(2 x 10)/(1 x 10)] - [(3 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 20/10 - 3/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (20/1 - 3/1)
= 1/10 x (20 - 3)

step 7Simplify the above expression further:
= 1/10 x 17
= 17/10
2 - 3/10 = 17/10

Hence,
2 minus 3/10 as a fraction is 17/10.

2 - 3/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/1
Fraction B: 3/10

What to be found?
(2)-(3/10) = ?
Find what's the difference between 2 and 3/10.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 10), 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 10) and rewrite the equation as like the below:
= (2 x 10) - (3 x 1)/(1 x 10)

step 3 Simplify and rewrite the fraction:
= (20 - 3)/10
2 - 3/10 = 17/10

Hence,
2 minus 3/10 in fraction is 17/10
