To find out what number a different number is a certain percentage of, all we need to do is divide the known number by the percentage. To do THAT, we first need to convert the fraction into a decimal. We can do this by either dividing the percentage by 100, or (my personal shortcut) just shifting the decimal point over two places to the left.
60% = 0.6
Now, we just divide the known number by the decimal.
24 / 0.6 = 40
So that will be our answer. 24 is 60% of 40. Hope that helped! =)
60% is 6/10 s. 24/6=4,4*10=40
40 is your answer
Hope that helps

Rollie was succesful in losing weight he had a goal weight in mind he went on a diet for three months each month he would lose one third of the difference between his current weight and his goal weight and an additional three pounds at the end of three months he was just 3 pounds over his goal weight how many pounds did he lose in those three months? Explain
Answers
let's say that in the beginning he weighted x and at the end he weighted x-y, y being the number of kg he wanted to loose.
first month he lost y/3
then he lost: (y-y/3)/3 this is (2/3y)/3=2/9y explanation: ((y-y/3) is what he still needed to loose: y minus what he lost already
and then he lost (y-2/9y-1/3y)/3+3 (the +3 is his additional 3 pounts) (y-2/9y-1/3y)/3-3=(7/9y-3/9y)/3+3=4/27y+3
it's not just y/3 because each month he lost one third of what the needed to loose at the current time, not in totatl
and the weight at the end of the 3 months was still x-y+3, 3 pounds over his goal weight!
so: x -y/3-2/9y-4/27y-3=x-y+3
we can subtract x from both sides: -y/3-2/9y-4/27y-3=-y+3 add everything up:
-19/27y=-y+6
which means -19/27y=-y+6
y-6=19/27y
8/27y=6 4/27y=3 y=20.25
so... that's how much he wanted to loose, but he lost 3 less than that, so 23.25
ps. i hope I didn't make a mistake in counting, let me know if i did. In any case you know HOW to solve it now, try to do the calculations yourself to see if they're correct!
How do you find the slope of a line?
Answers
-- Pick any small piece of the line.
-- From the left end to the right end of that piece, measure how much the line rises or drops.
-- Measure how much horizontal distance that piece covers.
-- Divide the amount of rise or drop by the horizontal distance. That number is the slope of the line.
-- If the line drops as it goes from left to right, then the slope is negative.
