What you need to do is give these problems a common denominator. Which makes 3/21 and14/21 respectively. Logically, you need to walk 4/21 of the trail. This can’t be simplified further.

The mayor of a town receives 75% of the votes in a town election. If 680 people voted, how many votes did the mayor receive? 360

First you need to put everything as 1 unit. I'll convert both to fractions for now.
75% = 3/4

680/1 * 3/4

Cross Multiply

2040/4

Simplify

510

The mayor received 510 votes.

Nastasia [14]

Answer:

x = 15

Step-by-step explanation:

We know that 4x° + 8x° make a straight angle of 180°.

4x° + 8x° = 180°

12x° = 180°

12x = 180

x = 180/12 = 15
