2. Cross multiplication method.
1/2-2/8 using LCM Method:
What is 1/2 minus 2/8 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/8
What to be found?
1/2-2/8 = ?
Find what's the difference between 1/2 and 2/8.
step 2 Compare the denominators of fractions 1/2 and 2/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/8 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 1/2 and 2/8:
The LCM of 2 and 8 is 8.
step 4 Write the fractions 1/2 and 2/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-2/8
=(1 x 8)/(2 x 8)-(2 x 8)/(8 x 8)
step 5 Simplify the expression to have common denominator:
=4/8-2/8
step 6 Take the common values out and rewrite the above expression like the below:
=1/8 x (4/1-2/1)
=1/8 x (4 - 2)
step 7Simplify the above expression further:
=1/8 x 2
= 2/8
=1/4
1/2-2/8=1/4
Hence,
1/2 minus 2/8 equals to 1/4 in fraction.
1/2-2/8 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/8
What to be found?
1/2-2/8 = ?
Find what's the difference between 1/2 and 2/8.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 8), find the product of numerator of Fraction B and denominator of Fraction A (2 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 8) and rewrite the equation as like the below:
= (1 x 8) - (2 x 2)/(2 x 8)
step 3 Simplify and rewrite the fraction:
= (8 - 4)/16
= 4/16
= 1/4
1/2-2/8 = 1/4
Hence,
1/2 minus 2/8 = 1/4
