The skyscraper will have 78 floors when it is finished.
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
Let's assume that the total number of floors in the skyscraper is "x".
According to the problem, the builder has built 1/6 of the floors.
So the number of floors built by the builder is:
= (1/6)x
The problem also tells us that the builder has built 13 floors.
So we can set up the equation:
(1/6) x = 13
To solve for "x", we can multiply both sides by 6:
x = 78
Therefore,
The skyscraper will have 78 floors when it is finished.

Answer:
4 sets.
Step-by-step explanation:
We are asked to find the greatest number of sets you can make using 28 pens and 80 pencils.
To solve our given problem, we will find greatest common factor of 28 and 80.
Factors of 28: 1, 2, 4, 7, 14, 28.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
We can see that the greatest common factor of 28 and 80 is 4, therefore, you can make at-most 4 sets each having same number of pens and pencils.
The simplified expression of 28/12 is 2 1/3
From the question, we have the following parameters that can be used in our computation:
28/12
Divide 28 and 12 by 4
so, we have the following representation
28/12 = 7/3
Next, we have
28/12 = 2 1/3
Hence, the simplified expression is 2 1/3

18/30, is reduced to 9/15 then 3/5.
9/15 first, because 18 and 30 are both divisible by 2.
18÷2=9 and 30÷2=15.
Then how I got 3/5, was because both 9 and 15 are divisible by 3.
9÷3=3 and 15÷3=5 so the final answer that you are looking for, is 3/5.
Answer: 3/5
Step-by-step explanation: In order to write the fraction 18/30 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 18 and 30 which is 6.18 divided by 6 is 3 and 30 divided by 6 is 5 so 18/30 written in lowest terms is 3/5.
it will move in 1,000 days than it will move in 100 days = 26910m.
In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, given that,
a glacier in Alaska moves about 29.9 meters a day.
i.e. in 1000 days = 29.9* 1000
= 29900m
in 100 days = 2990m
now, we get,
it will move in 1,000 days than it will move in 100 days = 26910m.
