first you find a common denominator ( I chose 90 because 18 * 5 = 90)
then you have to do the same thing what you did to the numerator so you would do 7*5=35 and 3*18=54
so it would be
35/90 + 54/90 = 89/90
and then you can't simplify it so the
answer is 89/90
Answer:
89/90
Step-by-step explanation:
Given the expression,
7/18+3/5
We will find the Lowest Common Multiple of the denominator of both fraction and then add up. This gives;
7/18+3/5
The LCM of 18 and 5 is 90
= {7(5)+3(18)}/90
= (35+54)/90
= 89/90
The expression of the given fraction in its lowest term is 89/90 since no number can go in both 89 and 90 without leaving a remainder.
