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.
We can now cross multiply.
Now, we simplify the right side.
Divide both sides by 30 to isolate x.
And there's your answer! Hope this helped!
