Erin's family has completed 70% of a trip. They have traveled 35 miles. How far is the trip?

Alexxandr [17]

Answer:

Their trip is 50 mile long.

Step-by-step explanation:

I first divided 70 by 35 to get two.The two represents 1 mile = 2%. So then I subtracted 70 from 100 to get 30 then I divided 30 by 2 to get 15. Then I added 15 to the original 35 to get 50 miles for their 100%/destination of their trip. Hope this helps! Have a great day!
