2. Cross multiplication method.
(7/19) - (2/9) using LCM Method:
What is 7/19 minus 2/9 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/19
Fraction B: 2/9
What to be found?
(7/19) - (2/9) = ?
Find what's the difference between 7/19 and 2/9.
step 2 Compare the denominators of fractions 7/19 and 2/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/19 and 2/9 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 7/19 and 2/9:
The LCM of 19 and 9 is 171.
step 4 Write the fractions 7/19 and 2/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/19 - 2/9
= [(7 x 171)/(19 x 171)] - [(2 x 171)/(9 x 171)]
step 5 Simplify the expression to have common denominator:
= 63/171 - 38/171
step 6 Take the common values out and rewrite the above expression like the below:
= 1/171 x (63/1 - 38/1)
= 1/171 x (63 - 38)
step 7Simplify the above expression further:
= 1/171 x 25
= 25/171
7/19 - 2/9 = 25/171
Hence,
7/19 minus 2/9 as a fraction is 25/171.
7/19 - 2/9 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/19
Fraction B: 2/9
What to be found?
(7/19)-(2/9) = ?
Find what's the difference between 7/19 and 2/9.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 9), find the product of numerator of Fraction B and denominator of Fraction A (2 x 19), and find the product of both denominators of Fraction A and Fraction B (19 x 9) and rewrite the equation as like the below:
= (7 x 9) - (2 x 19)/(19 x 9)
step 3 Simplify and rewrite the fraction:
= (63 - 38)/171
7/19 - 2/9 = 25/171
Hence,
