The given expression is:
5 / 18 + 2 / 3
Note that if you are good with finding LCD, then that is good. Otherwise, notice how LCD is determined.
In order to simplify that expression, we need to determine the LCD of the fractions. That is: Find the LCM of 18 and 3. Factor out each term to get:
18 = 2 * 3²
3 = 3
Since the LCM is the smallest integer that is divided by two or more numbers, the LCM is 3² * 2 = 18.
Check!
18 / 18 = 1
18 / 3 = 6
Good! Then, this means that 18 is the LCM of 18 and 3.
Now, let's go back to the problem.
We are given to simplify 5 / 18 + 2 / 3. Since the LCD is 18, multiply the top and bottom by 6 for 2 / 3 to get:
5 / 18 + (2 / 3 * 6 / 6)
= 5 / 18 + 12 / 18
Finally, the expression is simplified to:
(5 + 12) / 18
= 17 / 18
Two thirds is twelve eighteenths. Seventeen eighteenths minus twelve eighteenths is five eighteenths.
Two thirds is twelve eighteenths, so seventeen eighteenths minus twelve eighteenths is five eighteenths.
5/18 is shorter.
Yes, two-thirds is equal to twelve eighteenths. When you simplify twelve eighteenths by dividing both the numerator and the denominator by six, you get two-thirds. Therefore, the two fractions represent the same value.
17/18 + 12/18 = 29/18
five and one third
five and one third.
no because it does not come out evenly
Five eights plus two thirds minus one fourth is equal to 1.04
