2. Cross multiplication method.
1/5+4 using LCM Method:
What is 1/5 plus 4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 4/1
What to be found?
1/5+4 = ?
Find what's the sum of 1/5 and 4.
step 2 Compare the denominators of fractions 1/5 and 4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 1/5 and 4 are not equal, it is said to be unlike fractions addition.
step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 1/5 and 4:
The LCM of 5 and 1 is 5.
step 4 Write the fractions 1/5 and 4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/5+4
=(1 x 5)/(5 x 5)+(4 x 5)/(1 x 5)
step 5 Simplify the expression to have common denominator:
=1/5+20/5
step 6 Take the common values out and rewrite the above expression like the below:
=1/5 x (1/1+20/1)
=1/5 x (1 + 20)
step 7Simplify the above expression further:
=1/5 x 21
=21/5
1/5+4=21/5
Hence,
1/5 plus 4 equals to 21/5 in fraction.
1/5+4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 4/1
What to be found?
1/5+4 = ?
Find what's the sum of 1/5 and 4.
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 (4 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 1) and rewrite the equation as like the below:
= (1 x 1) + (4 x 5)/(5 x 1)
step 3 Simplify and rewrite the fraction:
= (1 + 20)/5
1/5+4 = 21/5
Hence,
1/5 plus 4 = 21/5
