Answer 2

Answer: A, 63 minutes

Step-by-step explanation:

We can start by making this into two ratios. Isa finished 30% in 27 minutes, so 30/27 is our first ratio. We want to know how long it will take for the rest of the homework to be completed. 30% is finished already, which leaves 70% (100-30=70). The time left is x. Our second ratio is 70/x. Now, we can set the two ratios equal to each other to solve for x.

$\frac{30}{27} = \frac{70}{x}$

We can now cross multiply.

$30x= 27(70)$

Now, we simplify the right side.

$30x= 1890$

Divide both sides by 30 to isolate x.

$x= 63$

And there's your answer! Hope this helped!
