Sarah was given an exit slip with the problem: "45 is 75% of what?" Below is how she set up the equation with equivalent ratios. Was she correct ? Or is there an error that can be corrected?

1.yes, she is correct

2.no, she should have set it up x/45 = 100/45

3.no, she should have set it up 45/x =75/100

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
