There is no formula for finding prime numbers. The rule is just if a number is prime then it is divisible by 1 and itself
Answer:
Before adding, we need to make sure the denominators are the same. We can do so by multiplying the fraction by a common multiple. In this case, 3 is a multiple of 6, so we can change 1/2 to 3/6. 3/6 is still equal to 1/2, so nothing changes.
Now we have 3/6+1/6, which is 4/6 (add the numerator).
4/6 can be simplified to 2/3 and 2 is a multiple of 4 and 6.
So, therefore, the answer is 2/3.
Answer:
144+27y
Step-by-step explanation:
3x3(4x4+3y)
9(16+3y)
144+27y
5/6 and 2/9......least common denominator is 18
so 5/6 = 15/18 and 2/9 = 4/18
1/12 and 3/8...least common denominator is 24
so 1/12 = 2/24 and 3/8 = 9/24
5/9 and 2/15...least common denominator is 45
so 5/9 = 24/45 and 2/15 = 6/45
