15% of 200

25% of 200

35% of 100

30, 50, 35

Step-by-step explanation:

Just ask if you need an explanation.

30; 50; 35

Step-by-step explanation:

To do this we can convert the percentages tofractions

15%->15/100->3/20

25%->25/100->1/4

35%->35/100->7/20

We can just pit the decimal over 100 and simplify it to make the calculations easier. To simplify you just have to divide the numerator and denominator by the same number. x/x is equal to 1 which is why it works. However, x/y does not equal 1.

We can make 200 and 100 into fractions too, to make it easier to understand.

We do this by putting it over 1, since it doesn't change the value of the number.

3/20*200/1

Now the numerators multiply together, and the denominators multiply together. Quick reminder: numerator is on top, and denominator is on the bottom.

So our answer is

600/20

Which is

30.

Now the next one.

1/4*200/1=200/4

Simplify.

50.

Last one:

7/20*100/1=700/20

Simplify.

35.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
