Answer:
7/10 can't be simplified, 2/10->1/5
Step-by-step explanation:
7/10 cannot be simplified as 7 and 10 don't have any common factors other than 1
2/10 can be simplified by a factor of 2 to get 1/5
Multiply total students by the percentage:
600 x 80% = 600 x 0.80 = 480
480 students want more field trips.
Step 2 is wrong: 4x - x = 5x
X = -11 is the actual answer, pretty sure.
