2. Cross multiplication method.
3/9-8/3 using LCM Method:
What is 3/9 minus 8/3 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 8/3
What to be found?
3/9-8/3 = ?
Find what's the difference between 3/9 and 8/3.
step 2 Compare the denominators of fractions 3/9 and 8/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/9 and 8/3 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 3/9 and 8/3:
The LCM of 9 and 3 is 9.
step 4 Write the fractions 3/9 and 8/3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/9-8/3
=(3 x 9)/(9 x 9)-(8 x 9)/(3 x 9)
step 5 Simplify the expression to have common denominator:
=3/9-24/9
step 6 Take the common values out and rewrite the above expression like the below:
=1/9 x (3/1-24/1)
=1/9 x (3 - 24)
step 7Simplify the above expression further:
=1/9 x -21
= -21/9
=-7/3
3/9-8/3=-7/3
Hence,
3/9 minus 8/3 equals to -7/3 in fraction.
3/9-8/3 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/9
Fraction B: 8/3
What to be found?
3/9-8/3 = ?
Find what's the difference between 3/9 and 8/3.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 3), find the product of numerator of Fraction B and denominator of Fraction A (8 x 9), and find the product of both denominators of Fraction A and Fraction B (9 x 3) and rewrite the equation as like the below:
= (3 x 3) - (8 x 9)/(9 x 3)
step 3 Simplify and rewrite the fraction:
= (9 - 72)/27
= -63/27
= -7/3
3/9-8/3 = -7/3
Hence,
3/9 minus 8/3 = -7/3
