Anita earns $72 every 6 h to fix bicycles. How much money will she earn in 4 h if she is paid at the same rate?

$48 in 4 hr

Step-by-step explanation:

Let's set up two equal proportions and cross-multiply, putting the money on top and the hours on bottom.

Now we can cross-multiply:

72*4 = 6x

288 = 6x

x = 288/6 = $48

$48

Step-by-step explanation:

Amount : hour

$72 : 6

$X : 4

4/6 = X/72

X = 72 × 4/6

X = 48

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

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.
