3. in class today, 1/4 of the students wore shorts and
3/12 of the students wore jeans. which statement
correctly compares the fractions?
a. 1/4 = 3/12
b. 1/4 > 3/12
c. 3/12 < 1/4
d. 1/4 < 3/12

A.

Step-by-step explanation:

This is a case of equivalent fractions  which means that the fractions represent the same amount.

Why are they the same?  Because when you multiply or divide the same number up and down simultaneously, the fraction maintains its value. The rule to remember is:

What you do to the top of the fraction

you also have to do it to the bottom part!

Therefore, these fractions are actually the same:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

(-5,-28)

i graphed to on desmos.
