Learn how to find what is 1/3 minus 3/15 in fraction form just in a few minutes. We have covered the easiest method to write 1/3 - 3/15 as a fraction and decimal.
Summary: 1/3 minus 3/15
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 1/3 and 3/15 having identical denominators before starting adding the fractions. Find the LCM of denominators, 15 is the LCM of 3 and 15. Multiply the LCM 15 with all the numerators and denominators of both fractions (1/3 x 15/15) - (3/15 x 15/15) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 2/15.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/15 from 1/3. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/3 minus 3/15.
1. LCM method
2. Cross multiplication method.
1/3-3/15 using LCM Method:
What is 1/3 minus 3/15 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/3
Fraction B: 3/15
What to be found?
1/3-3/15 = ?
Find what's the difference between 1/3 and 3/15.
step 2 Compare the denominators of fractions 1/3 and 3/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/3 and 3/15 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 1/3 and 3/15:
The LCM of 3 and 15 is 15.
step 4 Write the fractions 1/3 and 3/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/3-3/15
=(1 x 15)/(3 x 15)-(3 x 15)/(15 x 15)
step 5 Simplify the expression to have common denominator:
=5/15-3/15
step 6 Take the common values out and rewrite the above expression like the below:
=1/15 x (5/1-3/1)
=1/15 x (5 - 3)
step 7Simplify the above expression further:
=1/15 x 2
=2/15
1/3-3/15=2/15
Hence,
1/3 minus 3/15 equals to 2/15 in fraction.
1/3-3/15 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/3
Fraction B: 3/15
What to be found?
1/3-3/15 = ?
Find what's the difference between 1/3 and 3/15.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 15), find the product of numerator of Fraction B and denominator of Fraction A (3 x 3), and find the product of both denominators of Fraction A and Fraction B (3 x 15) and rewrite the equation as like the below:
= (1 x 15) - (3 x 3)/(3 x 15)
step 3 Simplify and rewrite the fraction:
= (15 - 9)/45
= 6/45
= 2/15
1/3-3/15 = 2/15
Hence,
1/3 minus 3/15 = 2/15
