Always use this formula to find a percentage:
<span>% / 100 = Part / Whole</span> replace the given values:
40 / 100 = Part / 150
Cross multiply:
40 x 150 = 100 x Part, or
6000 = 100 x Part
Now, divide by 100 and get the answer:
Part = 6000 / 100 = <span>60</span>
Let's say that x represents hours that Elizabeth volunteers over 1 week. Katie volunteers x+3 and Siobhan x-1 hours per week. The equation that arises from condition in text is:
3*(x+3) = 3*(x + x-1)
x+3 = 2*x - 1
2*x - x= 3+1
x=4.
Elizabeth volunteers 7 hours
Katie volunteers 4 hours
Siobhan volunteers 3 hours
