Other Percentage - ACT Math

You divide the number of blue socks, 4, by the number of total socks, 11, giving you 36%.

Calculate the price of each Package Deal. A = $2500(1.3) = $3250, B = $2400 (1+3/9) = $3200. C = $3225, D = $3600. Remember that 1 = 9/9 for fraction addition. Package deal C’s wording is tricky, the tax is already included. Package Deal B is the best deal.

For Tim, his percentage was .875 or 87.5%. For Tony, his percentage was .90 or 90%. For Danny, his percentage was also .875 or 87.5%. Thus Tony was the best.

This problem requires simple arithmetic, 30% of 93 can be obtained by multiply 93 X .30 = 27.9 Rounding yields 28 years.

$ sales x % Commission = $ Commission

25000 x 0.05 = 1250

8,100 * 0.09 = 729

Amount of discount = original price – new price

% discount = amount of discount ÷ original price

% discount = 15/50 = 0.3 or 30%

Percentage = Students on Soccer Team / Total Number of Students

= 3/8 = .375 = 37.5%

There are three students involved in soccer. Read across the chart and two of them are also involved in newspaper.

Percentage = 2/Total Number of Students

= 2/8 = .25 = 25%

Subtract 3, 26, and 31 from 76 to figure out how many students got A's (16).

Verbal cues are "is" and "of." Is means equals and of means multiplication.

So the equation to solve becomes which equals 65.

So the equation to solve becomes or earned.

Verbal cues include "is" and "of." "Is" means equals and "of" means multiply.

So the equation to solve becomes or .

The number of minutes in a week is:

The number of minutes spent studying is:

6.8%

To find the percentage of a number, convert the percentage into a decimal by diving the percent by 100.

,

then multiply that decimal by the number.

For percentage problems, the easiest way to start is by remembering that the word "of" is best translated as a multiplication, while the word "is" is best translated by an equals sign. Thus, for the information provided, we can write the equation:

Remember, though, that will represent a percentage in a decimal form and will need to be translated. (There are other ways of doing this, but most students remember to do this translation at the end naturally.)

Solving for , you get:

This is .

For percentage problems, the easiest way to start is by remembering that the word "of" is best translated as a multiplication, while the word "is" is best translated by an equals sign. Thus, for the information provided, we can write the equation:

Solving for , you get:

Alternatively you could first calculate of , which is , and then calculate of that, and you would arrive at the same answer.

The most common way to do a problem like this is to begin by applying the first discount, calculating the amount to be removed from the original price. This is done by multiplying the original price by . This gives you . This is then subtracted from to give you . Once again, this new number is multiplied, now by . This gives you . When subtracted from , this gives you a final price of , or the rounded value of .

A simpler way to do this is to realize that the first price reduction makes the new price to be of the original. The second will then make the price to be of the intermediary price. Thus, you could easily compute:

As of right now, the man has pounds of body fat. If this increases by , we he will gain or more pounds of body fat. This means that he will have a total of pounds of body fat. Also, it means that his total weight will be pounds. Therefore, his muscle, as a percent of his total weight will be:
