What is 7/1 - 2/3 in fraction?
7/1 - 2/3 equals to 19/3 in fraction form.
Learn how to find what is 7/1 minus 2/3 in fraction form just in a few minutes. We have covered the easiest method to write 7/1 - 2/3 as a fraction and decimal.
Summary: 7/1 minus 2/3 = 19/3
Since both fractions have unequal denominators, 7/1 minus 2/3 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/1 and fraction 2/3 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 3. 3 is the LCM of 1 and 3. Multiplying the LCM 3 with the numerators and denominators of both fractions (7/1 x 3/3) - (2/3 x 3/3), and simplify further in order to have the common denominator. So the equivalent fraction for 7/1 is 21/3 and for 2/3 is 2/3. By simplifying this fraction subtraction 21/3 - 2/3, it becomes 19/3.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/3 from 7/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/1 minus 2/3.
1. LCM method
2. Cross multiplication method.
(7/1) - (2/3) using LCM Method:
What is 7/1 minus 2/3 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/1
Fraction B: 2/3
What to be found?
(7/1) - (2/3) = ?
Find what's the difference between 7/1 and 2/3.
step 2 Compare the denominators of fractions 7/1 and 2/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/1 and 2/3 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 7/1 and 2/3:
The LCM of 1 and 3 is 3.
step 4 Write the fractions 7/1 and 2/3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/1 - 2/3
= [(7 x 3)/(1 x 3)] - [(2 x 3)/(3 x 3)]
step 5 Simplify the expression to have common denominator:
= 21/3 - 2/3
step 6 Take the common values out and rewrite the above expression like the below:
= 1/3 x (21/1 - 2/1)
= 1/3 x (21 - 2)
step 7Simplify the above expression further:
= 1/3 x 19
= 19/3
7/1 - 2/3 = 19/3
Hence,
7/1 minus 2/3 as a fraction is 19/3.
7/1 - 2/3 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/1
Fraction B: 2/3
What to be found?
(7/1)-(2/3) = ?
Find what's the difference between 7/1 and 2/3.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 3), find the product of numerator of Fraction B and denominator of Fraction A (2 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 3) and rewrite the equation as like the below:
= (7 x 3) - (2 x 1)/(1 x 3)
step 3 Simplify and rewrite the fraction:
= (21 - 2)/3
7/1 - 2/3 = 19/3
Hence,
7/1 minus 2/3 in fraction is 19/3
