2in=min
The rate is 2 inches per minute
Final answer:
The unit rate for the given problem, 1/7 inch per 1/14 minute, is calculated by dividing the inches by the minutes. This simplifies to 2 inches per minute.
Explanation:
In mathematics, a unit rate is a rate in which the second number (or denominator) is one. When you are asked to write the rate 1/7 inch per 1/14 minute as a unit rate, you are being asked to find a rate that tells you how much of each quantity occurs for each single unit of the other quantity, in this case for 1 minute. To calculate this unit rate, divide the quantity in inches by the quantity in minutes.
In this problem, you can find the required unit rate by dividing (1/7) by (1/14), which simplifies to (1/7) * (14/1) = 2 inches. So, the unit rate for this problem is 2 inches per minute.

What is common factor? What is a mathematical equation? What is Probability?
- A common factor is a whole number which is a factor of two or more numbers. The highest common factor (HCF) is the greatest factor that will divide into two or more numbers. The lowest common multiple(LCM) is the smallest multiple that is common to two or more numbers.
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions.
- Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have three numbers 24, 56 and 72.
The factors of 24 are : 1, 2, 3, 4, 6, 8, 12, 24
The factors of 56 are : 1, 2, 4, 7, 8, 14, 28, 56
The factors of 72 are : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Therefore, the greatestcommon factor will be 8.

Answer:
Step-by-step explanation: honestly don’t know
20-12=8
2/5-3/5= -1/5
Since its negative, you have to take 1 off of the final answer and put 4/5 so the answer is 7 4/5
Another way is making it a decimal
12 3/5= 12.6
20 2/5= 20.4
20.4-12.6= 7.8
7.8=7 4/5
