2. Cross multiplication method.
1/2-17 using LCM Method:
What is 1/2 minus 17 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 17/1
What to be found?
1/2-17 = ?
Find what's the difference between 1/2 and 17.
step 2 Compare the denominators of fractions 1/2 and 17 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 17 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 17:
The LCM of 2 and 1 is 2.
step 4 Write the fractions 1/2 and 17 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-17
=(1 x 2)/(2 x 2)-(17 x 2)/(1 x 2)
step 5 Simplify the expression to have common denominator:
=1/2-34/2
step 6 Take the common values out and rewrite the above expression like the below:
=1/2 x (1/1-34/1)
=1/2 x (1 - 34)
step 7Simplify the above expression further:
=1/2 x -33
=-33/2
1/2-17=-33/2
Hence,
1/2 minus 17 equals to -33/2 in fraction.
1/2-17 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 17/1
What to be found?
1/2-17 = ?
Find what's the difference between 1/2 and 17.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 1), find the product of numerator of Fraction B and denominator of Fraction A (17 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 1) and rewrite the equation as like the below:
= (1 x 1) - (17 x 2)/(2 x 1)
step 3 Simplify and rewrite the fraction:
= (1 - 34)/2
1/2-17 = -33/2
Hence,
1/2 minus 17 = -33/2
