Answer:
3:5 is the ratio.
Step-by-step explanation:
The ratio of the number of steps of father to number of steps of son is 3:5.
The table forms as follows:
Steps by father Steps by son
3 5
6 10
9 15
12 20
15 25
a) The ratio of the number of steps of father to number of steps of son will be 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
a) We can continue finding equivalent ratios by multiplying both sides of the ratio by different numbers, such as 3, 4, or any other value.
Multiply the first term by 2 to get 3 * 2 = 6. Multiply the second term by 2 to get 5 * 2 = 10.
- The equivalent ratio is 6:10.
In the ratio table, we can observe that the values of the ratios are always in the form of a fraction or as a simplified fraction.
=The ratios we have found so far, such as
3:5 and 6:10, = 3/5 and 3/5 respectively.
Thus the ratio of the number of steps of father to number of steps of son is 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25

What is a fraction?
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.

I can't imagine. All you have to do is pick any old number, divide the
top and bottom of the fraction by it, and you'll have a new fraction that's
equivalent to 50/100 . And if the number you pick is 2, 5, 10, or 25,
then the new fraction will even have whole numbers on top and bottom.
You can even pick any old number, multiply the top and bottom of the
fraction by it, and you'll have a new fraction that's equivalent to 50/100 .
Can't imagine what's so hard about that.
