Ratios can be described in different ways, if you were given a fraction such as 2/4 then we would put in 3 ways like 2/4, 2:4, and 2 to 4. So basically in any rule with fractions or anything else like that you'd have to explain it in 3 ways like my example shows.

Hopefully this helped. :)

A rectangular pool is 40 feet by 20 feet. The portion of the pool that is reserved for recreational swimming is 20 ft by 10 ft.
Alik [6]
Total pool = 40 by 20, or 800 feet
Recreational = 20 by 10, or 200 feet

Subtract the recreational part of the pool from the total pool, your answer should be:

600 square feet are reserved for the swim team.

In Lucille’s class, 35% of the students have blond hair. There are 20 students in the class. How many students have blond hair.
MrRissso [65]

Answer:

7 the answer is 7

Step-by-step explanation:

1. We assume, that the number 20 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 20 is 100%, so we can write it down as 20=100%.

4. We know, that x is 35% of the output value, so we can write it down as x=35%.

5. Now we have two simple equations:

1) 20=100%

2) x=35%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

20/x=100%/35%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 35% of 20

20/x=100/35

(20/x)*x=(100/35)*x       -

20=2.85714285714*x       -

20/2.85714285714=x

7=x

x=7

now we have:

35% of 20=7

we multiply both sides by x

then we divide both sides by 2.85714285714 to get x
