What type of problems can you solve using operations with rational numbers?
Answer:
like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers
All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
A rational number is a number in form of p/q where p and q both will be integers.
Since p and q both are integers so we can multiply by other fractions for example (2/3) x (4/6).
We can divide by another integer for example (2/3)/4.
Hence "All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers".

Please show the work like attaching an image of the work or just doing it on here, I need to see the process and steps, I’ll mark whoever does the work correctly brainly :)
Answer: B: 3/8 x 1/5
Step-by-step explanation:
It is B because when you are dividing fractions you do keep, change, flip.
1. 3/8 divided by 5
2. 3/8 divided by 5/1
3. Do KCF, 3/8 (keep) x (change) 1/5 (flip)
4. Equals 3/8 x 1/5
The division of the fraction number to the whole number will be (3 / 8) x (1 / 5). Then the correct option is B.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The fraction number is 3/8 and the whole number is 5. Then the division of the fraction number and the whole number is calculated as,
⇒ (3 / 8) ÷ (5 / 1)
⇒ (3 / 8) / (5 / 1)
⇒ (3 / 8) x (1 / 5)
The division of the fraction number to the whole number will be (3 / 8) x (1 / 5). Then the correct option is B.

During a snowstorm, Ruby tracked the amount of snow on the ground. When the storm began, there was 1 inch of snow on the ground. For the first 3 hours of the storm, snow fell at a constant rate of 1 inch per hour. The storm then stopped for 4 hours and then started again at a constant rate of 3 inches per hour for the next 5 hours. As soon as the storm stopped again, the sun came out and melted the snow for the next 2 hours at a constant rate of 4 inches per hour. Make a graph showing the inches of snow on the ground over time using the data that Ruby collected.

Pentagon ABCDE is similar to pentagon RSTUV. The perimeter of pentagon ABCDE is 36.8 centimeters.
What is the length of ST ?
18 cm
25.8 cm
15 cm
19.8 cm
Answer:
15cm
Step-by-step explanation:
Since BC is like ST but smaller, we have to find the length of BC then find the proportion for ST.
Length of BC = 36.8 - 4.4 - 13.2 - 2.2 - 11
= 6
Scale = [tex]\frac{33}{13.2}[/tex]
Length of ST = [tex]\frac{33}{13.2}[/tex] × 6
= 15
The length ST of the pentagon RSTUV is 7.36 centimeters.
What is pentagon?A polygon with 5 sides is a pentagon. The total sum of the internal angles of a pentagon is 540°.
Given is that Pentagon ABCDE is similar to pentagon RSTUV.
Since the pentagon ABCDE is similar to the pentagon RSTUV, we can conclude that the perimeter of the pentagon ABCDE is similar to that of pentagon RSTUV. Now, the sides of the pentagon are equal in length. So, we can write that -
ST = Perimeter/5
ST = 36.8/5
ST = 7.36
Therefore, the length ST of the pentagon RSTUV is 7.36 centimeters.
