2. Cross multiplication method.
3/5-11/15 using LCM Method:
What is 3/5 minus 11/15 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 11/15
What to be found?
3/5-11/15 = ?
Find what's the difference between 3/5 and 11/15.
step 2 Compare the denominators of fractions 3/5 and 11/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/5 and 11/15 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 3/5 and 11/15:
The LCM of 5 and 15 is 15.
step 4 Write the fractions 3/5 and 11/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/5-11/15
=(3 x 15)/(5 x 15)-(11 x 15)/(15 x 15)
step 5 Simplify the expression to have common denominator:
=9/15-11/15
step 6 Take the common values out and rewrite the above expression like the below:
=1/15 x (9/1-11/1)
=1/15 x (9 - 11)
step 7Simplify the above expression further:
=1/15 x -2
=-2/15
3/5-11/15=-2/15
Hence,
3/5 minus 11/15 equals to -2/15 in fraction.
3/5-11/15 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 11/15
What to be found?
3/5-11/15 = ?
Find what's the difference between 3/5 and 11/15.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 15), find the product of numerator of Fraction B and denominator of Fraction A (11 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 15) and rewrite the equation as like the below:
= (3 x 15) - (11 x 5)/(5 x 15)
step 3 Simplify and rewrite the fraction:
= (45 - 55)/75
= -10/75
= -2/15
3/5-11/15 = -2/15
Hence,
3/5 minus 11/15 = -2/15
