Emily and her children went into a grocery store and she bought $20.80 worth of
bananas and peaches. Each banana costs $0.80 and each peach costs $2. She bought
a total of 14 bananas and peaches altogether. Write a system of equations that could
be used to determine the number of bananas and the number of peaches that Emily
bought. Define the variables that you use to write the system.

pls mark as brainliest

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
