Write each percentage as a fraction and as a decimal

In order to Write down the percent divided by 100 ==>  percent/100 then  In we check if the   percent is not a whole number,if not  then we need to multiply both top and bottom by 10 for every number that comes after the decimal point. (For example, in case there is one number after the decimal point  then we use 10, if there are two numbers then use 100 and so on )   lastly  we Simplify reduce the percentage to  the fraction

Step-by-step explanation:

To convert a Percentange  to a Fraction  we need to follow the below mentioned  steps:

1) Write down the percent divided by 100 ==>  percent/100

2) In case  percent is not a whole number, if not then we need to multiply both top and bottom by 10 for every number that comes after the decimal point.

(For example, in case there is one number after the decimal point  then we use 10, if there are two numbers then use 100 and so on )

3)Then we Simplify reduce the percentage to  the fraction

For Example :Convert 25% to fraction then

1) 25% =25/100

2) Now in this case the percentage is a whole number so we go directly to step 3

3) 25/100=5/20= 1/4

25/100  is called a decimal fraction and  1/4 is called a common fraction

Now if we need to convert a Percentage into Decimal then:

Let us consider the Percentage to be 25%

The easiest way to divide by 100 is to

1)we divide the number  by 100, and remove the  percentage sign. ==>25/100

2)Now we move the decimal point 2 places to the left of the percentage number ==>.25

So the decimal form of the 25% is.25

yeah i know the problem you need. i am taking it right now. the answer is step 3

a) 40 more; b) old factory:   10%, new factory:   16%; c) week 4

explanation:

a) at week 0, we see in the graph that the new factory produces 190 specialty items.  

using the function, substituting 0 in for w,

this is a difference of 230-190 = 40.

b) the function for the old factory is written in the form f(x) = a(1+r)ˣ, where a is the original amount, x is the amount of time and r is the growth rate.   the equation for the old factory is ; 230 is in place of a and is the original amount; w is the amount of time; which means 1+r = 1.1.   this means that r must be 0.1 or 10%.

for the new factory, we find the percent of increase to find the growth rate; the formula for this is

between the first two points, the amount of change is 220-190 = 30; this gives us

30/190 = 0.158 ≈ 0.16 = 16%

c) at week 0, the old factory has 230 while the new factory has 190.

at week 1, the old factory has 230(1.1) = 253 while the new factory has 220.

at week 2, the old factory has 230(1.1²) = 278.3 while the new factory has 252.

at week 3, the old factory has 230(1.1³) = 306.13 while the new factory has 290.

at week 4, the old factory has 230(1.1⁴) = 336.743 while the new factory has 337.   this is the first week that the new factory surpasses the old.
