So, first you use what you already know. Put 60 over 100, since 60 is your percentage; put 192 as your denominator, with a "?" as the numerator to represent the missing/unknown part of the fraction. Next, cross multiply, or multiply 60x192 (which is 11520), then divide the product by 100. Your final answer is 115.2. Hope you found this helpful!
Let
x------> hours worked by Sara last week
y------> hours worked by Joan last week
z------> hours worked by Erin last week
we know that
x=28 hours ------> equation 1
y=x-6-----> equation 2
substitute the value of x in equation 2
y=28-6=22 hours
z=y/2------> equation 3
substitute the value of y in the equation 3
z=22/2=11 hours
<u>the answer is</u>
Sara worked 28 hours last week
Joan worked 22 hours last week
Erin worked 11 hours last week
