This can be solved by using a simple algebraic equation.
For example, in the first column, Caleb worked 5 hours. We do not know how much he makes per hour, so let that be x. He earned a total of $36.25, so the equation can be written as 5x=36.25.
Divide by 5 on both sides, and you get x= 7.25
He earns $7.25 per hour of work.
Repeat this for all the workers:
Jeremy: 7.5x=65.25
x= $8.70
Maria: 4.25x=34.00
x= $8
Rosa: 8x=54.00
x= $6.75
Jeremy has the greatest hourly rate
It seems like they're both divisible by 8, so let's do that.
40/64 = 5/8
There is no way to divide 5/8 while keeping the whole numbers.
Therefore, 40/64 has an equivalent fraction of 5/8.
However, that is the simplest equivalent fraction. Other ones can include:
40/64 = 80/128 (multiply both sides by 2)
40/64 = 20/32 (divide both sides by 2)
As long as you only multiplied or divided both the numerator and the denominator with same values, it is considered as an equivalent fraction as the fraction before
