4/1 + 9/10 as a fraction

Learn how to find what is 4/1 plus 9/10 in fraction form just in a few minutes. We have covered the easiest method to write 4/1 + 9/10 as a fraction and decimal.

Summary: 4/1 plus 9/10 = 49/10
Since both fractions have unequal denominators, 4/1 plus 9/10 is an unlike fractions addition. For adding unlike fractions, you have to first find the equivalent fractions for fraction 4/1 and fraction 9/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 10. 10 is the LCM of 1 and 10. Multiplying the LCM 10 with the numerators and denominators of both fractions (4/1 x 10/10) + (9/10 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 4/1 is 40/10 and for 9/10 is 9/10. By simplifying this fraction addition 40/10 + 9/10, it becomes 49/10.

The below workout with step by step calculation shows how to find the equivalent fraction between 4/1 and 9/10 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 4/1 plus 9/10 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.

(4/1) + (9/10) using LCM Method:
What is 4/1 plus 9/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/1
Fraction B: 9/10

What to be found?
(4/1) + (9/10) = ?
Find what's the sum of 4/1 and 9/10.

step 2 Compare the denominators of fractions 4/1 and 9/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 4/1 and 9/10 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 4/1 and 9/10:
The LCM of 1 and 10 is 10.

step 4 Write the fractions 4/1 and 9/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/1 + 9/10
= [(4 x 10)/(1 x 10)] + [(9 x 10)/(10 x 10)]

step 5 Simplify the expression to have common denominator:
= 40/10 + 9/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (40/1 + 9/1)
= 1/10 x (40 + 9)

step 7Simplify the above expression further:
= 1/10 x 49
= 49/10
4/1 + 9/10 = 49/10

Hence,
4/1 plus 9/10 as a fraction is 49/10.
