Answer 1

1: A

2: D

Explanation:

For number one, to find the answer you simply divide the price of the cans by the amount of the cans to find the price for each one, 10.88 / 7 is 1.55 which is the lowest price per can.

For number two, to solve it, you need to find out the lowest number possible to go into both the numerator (14) and the denominator (35) an even amount of times. What I mean by this is if you have the fraction 10/20 you wanna find the highest number possible to divide both numbers evenly. So, when 10/20 is simplified it will be 1/2. For 14/35 when simplified it will be 2/5.
