Answer:
whats the question?
Step-by-step explanation:
So you already know the difference between the new number and original number, so all you have to do now is plug it in to this: Percentage Change=Difference/Original Number x100. So 17.99/257=.07x100 which equals 7%. So B is the correct answer.
The common denominators of ¹/₄ and ⁷/₁₀ are; 20 and 40
<h3>How to find the denominator?</h3>
The numerator of a fraction is the top value while the denominator of a fraction is the value at the bottom.
Now, we want to find the common denominator of ¹/₄ and ⁷/₁₀.
The common denominator can't be less than 4 or 10 and so has to be at least two terms that are divisible by 4 and 10. The next two common denominators that are greater than 10 but divisible by both 4 and 10 are 20.
