2. Cross multiplication method.
3/9-4/14 using LCM Method:
What is 3/9 minus 4/14 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 4/14
What to be found?
3/9-4/14 = ?
Find what's the difference between 3/9 and 4/14.
step 2 Compare the denominators of fractions 3/9 and 4/14 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/9 and 4/14 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 3/9 and 4/14:
The LCM of 9 and 14 is 126.
step 4 Write the fractions 3/9 and 4/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/9-4/14
=(3 x 126)/(9 x 126)-(4 x 126)/(14 x 126)
step 5 Simplify the expression to have common denominator:
=42/126-36/126
step 6 Take the common values out and rewrite the above expression like the below:
=1/126 x (42/1-36/1)
=1/126 x (42 - 36)
step 7Simplify the above expression further:
=1/126 x 6
= 6/126
=1/21
3/9-4/14=1/21
Hence,
3/9 minus 4/14 equals to 1/21 in fraction.
3/9-4/14 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 4/14
What to be found?
3/9-4/14 = ?
Find what's the difference between 3/9 and 4/14.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 14), find the product of numerator of Fraction B and denominator of Fraction A (4 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 14) and rewrite the equation as like the below:
= (3 x 14) - (4 x 9)/(9 x 14)
step 3 Simplify and rewrite the fraction:
= (42 - 36)/126
= 6/126
= 1/21
3/9-4/14 = 1/21
