I organized an ocean cleanup and we collected a total of 25 pounds of garbage.16 pounds of garbage consisted of plastic.What percent of the garbage was plastic?

Answer 1

The answer is #64%#.

In order to find out the percentage from a situation, we must set up two ratios.

#16/25 = "? %"/"100%"#
is the equation you will have to use to find the percentage of how much is made out of plastic. The first way is to use cross-multiply. Meaning you will have to multiply #16# by #100# to gain #1600# as your product. Dividing #1600# by #25# gives you #64%#.
The second way to see if it's correct is by dividing #16# by #25#. This gives you a decimal of #0.64#. By doing #0.64 xx 100#, it gives you #64#. Therefore, #64%# of the trash collected was plastic.

Answer 2

64%

#color(blue)("Preamble")#

Percentage can be written in two ways. Although they look different they both mean the same thing.

Example: 30 percent #-> 30% -> 30/100#
Percentage really is a special fraction. What makes it special is that the bottom number (denominator) is ALWAYS 100. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(blue)("Answering the question")#

All the plastic collected weighed 25 pounds Of this there was 16 pound of plastic

The amount of plastic expressed as a fraction of the whole is #16/25#

We need to change this to percentage so the bottom number (denominator) has to end up as being 100.

Multiply by 1 and you do not change the value. However, 1 comes in many forms.

#color(green)(16/25color(red)(xx1) color(white)("d") ->color(white)("d")16/25color(red)(xx4/4) )#
#color(green)(color(white)("ddddddd")->color(white)("d")(16xx4)/(25xx4))#
#color(green)(color(white)("ddddddd")->color(white)("dd")64/100)# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Think of this as #64xx1/100#
Think of % as being the same as #xx1/100#
So #64xx1/100 ->64%#

Answer 3

To find the percentage of the garbage that was plastic, divide the weight of the plastic garbage (16 pounds) by the total weight of the garbage collected (25 pounds), then multiply by 100.

(16 / 25) * 100 = 64%

So, 64% of the garbage collected was plastic.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
