5 is 5% of what number? I know the answer is 100, but what are the steps to get 100?
Answers
5% of x=5
(5/100)x=5
x=(5*100) / 5
x=500/5
x=100
Answer: the number is 100.
_ _
x 100
5 over x is equivalent to 5% (5 over 100)
Cross multiply
Five times 100 is five hundred. Divide by five. x=100

1.16 rounded to its nearest tenths is 1.2.
What is place value?
The placevalue of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 thousandths place value
We have,
1.16
The number 1 after the decimal point is in the tenthplacevalue.
Now,
Since 6 is greaterthan 5 tenth place value will be rounded to the next number.
So,
1.16 rounded to the nearest tenths.
= 1.2
Thus,
1.16 rounded to its nearest tenths is 1.2.

You want to round to the tenths, and the tenths spot is taken by a 1.
So, you use the 6 (in the hundredths spot) and since it is over 5, you boost it up.
The 1 will now become a 2, so the answer is 1.2.
A helpful phrase I use is “five or above, give it a shove. Four or below, keep it low.”

Answer:
Kid tickets = $4
Adult tickets = $7
Step-by-step explanation:
3K+9A=75 this is the equation for this week, it shows how many adult and kid tickets were added up to a total of $75
8K+5A=67 this is the equation for last week, it shows how many adult and kid tickets were added up to a total of $67
here, we can use substitution or elimination with these two formulas:
3K+9A=75
8K+5A=67
Substitution method; solve one equation for a variable and use the value in the other equation, such as follows:
3K+9A=75 we will solve for the variable, K, seeing that both 9 and 75 are divisible by K's coefficient of 3
3K+9A=75 subtract 9A from both sides to get 3K=75-9A
3K=75-9A divide by 3 to get K by itself, leaving us with K=25-3A
now that we know K=25-3A, we can substitute it's new value in the other equation: 8K+5A=67
8(25-3A)+5A=67 we will multiply out to get rid of the parentheses first because of PEMDAS
200-24A+54=67 now we add like terms to simplify to 200-19A=67
now we subtract 200 from both sides to get -19A=-133
now we divide by -19 to get A by itself A=7
Now that we have A, we can plug it into any equation to get K
let's use the first equation: 3K+9A=75
3K+9(7)=75 this simplifies to 3K+63=75 and then 3K=12 we divide by 3 to get K=4
With this information, we know now that each Kid ticket cost $4 and each adult ticket cost $7
Now, if we were to use elimination, it would look like this because we eliminate one variable like I do here:
our Greatest Common Factor (GCF) is 24 between the Ks
3K+9A=75 we can multiply this whole equation by 8
8K+5A=67 and this equation by -3
8(3K+9A=75) = 24K+72A=600
-3(8K+5A=67) = -24K-15A=-201
if we set this up like subtraction, we can eliminate K because 24 is cancelled out by -24 and we are left with this:
72A=600
-15A=-201
we add the equations to get this:
57A=399 and now we divide to get A
A=7
Again, now that we have A, we use it in an equation, just like in Substitution. This time I will demonstrate with the second equation: 8K+5A=67
8K+5(7)=67 ypu should know the steps by now, so I am going to skip to the last step:
8K=32 K=4
Hope that helps!

First, we can start by changing 2 2/3 to an improper fraction. To do this, we can use the rule: a b/c = ac+b/c. All we need to do is insert our numbers into the form of the rule.
Second, we can now start simplifying. (2 × 3 = 6 and 6 + 2 = 8).
Third, now we have change our denominators to be the same. To do this, we can start out by finding the least common denominator (LCD). List the multiples of both of the current denominators (3 and 5) and find the first common one.
Multiples of 3: 3, 6, 9, 12, 15
Multiples of 5: 5, 10, 15
Since 15 is our first common multiple, it is now our LCD.
Fourth, now we can multiply to change our denominators. Using our current denominators, we have to multiply by let's say (x / a variable). Basically, what can you multiply by 3 to get 15? That would be (3 × 5 = 15). For our other fraction, what would we multiply by 5 to get 15? (5 × 3 = 15). Remember, whatever you do to the bottom you must do to the top.
Fifth, we can now combine our denominators, which will make us have to add both of the numerators together.
Sixth, our last step is to convert the fraction into a mixed fraction. How you do this is to divide the numerator by the denominator. We would set up something like this: 31 ÷ 15 = 2.066667. That decimal in fraction form is 2 1/15, which is our answer.
