The below workout with step by step calculation shows how to find the equivalent fraction between 7/10 and 1/4 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/10 plus 1/4 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
7/10+1/4 using LCM Method:
What is 7/10 plus 1/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/10
Fraction B: 1/4
What to be found?
7/10+1/4 = ?
Find what's the sum of 7/10 and 1/4.
step 2 Compare the denominators of fractions 7/10 and 1/4 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/10 and 1/4 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 7/10 and 1/4:
The LCM of 10 and 4 is 20.
step 4 Write the fractions 7/10 and 1/4 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/10+1/4
=(7 x 20)/(10 x 20)+(1 x 20)/(4 x 20)
step 5 Simplify the expression to have common denominator:
=14/20+5/20
step 6 Take the common values out and rewrite the above expression like the below:
=1/20 x (14/1+5/1)
=1/20 x (14 + 5)
step 7Simplify the above expression further:
=1/20 x 19
=19/20
7/10+1/4=19/20
Hence,
7/10 plus 1/4 equals to 19/20 in fraction.
7/10+1/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/10
Fraction B: 1/4
What to be found?
7/10+1/4 = ?
Find what's the sum of 7/10 and 1/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), find the product of numerator of Fraction B and denominator of Fraction A (1 x 10), and find the product of both denominators of Fraction A and Fraction B (10 x 4) and rewrite the equation as like the below:
= (7 x 4) + (1 x 10)/(10 x 4)
step 3 Simplify and rewrite the fraction:
= (28 + 10)/40
= 38/40
= 19/20
7/10+1/4 = 19/20
Hence,
7/10 plus 1/4 = 19/20
