Answer:

Step-by-step explanation:

The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.

(5 workers) × (8/5) = 8 workers

8 workers are needed to complete the project in 15 days.

Question #2 What is the difference?

Answer:

B $\frac{b-10}{b-1}$

Step-by-step explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this : $\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}$

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get $\frac{b^{2} - 8b - 20}{(b-1)(b-2)}$

now factoring the numerator we will end like this

$\frac{(b-10)(b+2)}{(b-1)(b+2)}$

we will then end up with the answer.

Hope this helps.
