How do you use a strategy of 30%of 900?
Julli [10]

Answer: 2 7 0

Step-by-step explanation:

1. We assume, that the number 900 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 900 is 100%, so we can write it down as 900=100%.

4. We know, that x is 30% of the output value, so we can write it down as x=30%.

5. Now we have two simple equations:

1) 900=100%

2) x=30%

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:

900/x=100%/30%

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 30% of 900

900/x=100/30

(900/x)*x=(100/30)*x       - we multiply both sides of the equation by x

900=3.33333333333*x       - we divide both sides of the equation by (3.33333333333) to get x

900/3.33333333333=x

270=x

x=270

now we have:

30% of 900=270

73.7 is 55% of what number?
Vera_Pavlovna [14]

Answer:

a.) Let the total number be : x

∴(73.7÷x) ×100 = 55%

∴x= (73.7×100) ÷ 55

=> 7370÷55

∴x=134

Thus, Option-A.

----------------------------------------------------

b.) Let the percentage  be : x

∴x= (46÷65) ×100  

∴x= (0.707) × 100

∴x=70.7%

Thus, Option-B.
