The least common multiple of 8 and 9 is 72.
2/8 x (9/9) = 18/72
3/9 x (8/8) = 24/72
Step 1: Convert fractions so they have a common denominator
Step 2: Multiply both fractions by the common denominator
Step 3: Simplify by dividing by the highest common factor
I hope this helps

Answers: Choice A and Choice B</h3>
Explanation:
The 4 in the denominator of the original fraction is the same as 4^1
Then use the rule that (a^b)/(a^c) = a^(b-c). That means (4^32)/(4^1) = 4^(32-1) = 4^31 pointing us to choice B as one of the answers
Then notice how (8^31)/(2^31) = (8/2)^31 = 4^31, meaning choice A is the other answer. The rule I used is (a/b)^c = (a^c)/(b^c).
Choice C is not equivalent to the original expression because 4^4*4^8 = 4^(4+8) = 4^12, which is significantly smaller than 4^31.
Choice D can be ruled out as well because 4^33 is larger than 4^31.
Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1
