Jeremy worked for 8 1/2 hours building model airplanes. If each airplane takes him 1 2/5 hours to make, how many models did he build?(1 point)
Responses
11 9/10 models
10/119 of a model
6 1/14 models
14/85
To find the number of models Jeremy built, divide the total number of hours he worked (8 1/2 hours) by the time it takes him to make each model (1 2/5 hours).
8 1/2 hours = 17/2 hours
1 2/5 hours = 7/5 hours
Dividing 17/2 hours by 7/5 hours, we get:
(17/2) / (7/5) = (17/2) * (5/7) = (17 * 5) / (2 * 7) = 85/14
So Jeremy built 85/14 models, which is approximately equal to 6 1/14 models.
The closest answer choice is 6 1/14 models.
