How do you reduce a ratio?

How to Simplify a Ratio A : B when A and B are both whole numbers

List the factors of A

List the factors of B

Find the greatest common factor of A and B, GCF(A, B)

Divide A and B each by the GCF

Use the whole number results to rewrite the ratio in simplest form

If the GCF = 1 then the ratio is already in simplest form.

How to Simplify a Ratio A : B when A and B are not whole numbers, in this order

If A or B are mixed numbers convert mixed numbers to improper fractions

If A or B are decimal numbers multiply both values by the same factor of 10 that will eliminate all decimal places

If one value is a fraction and the other a whole number, reduce the fraction to a whole number if you can or turn the whole number into a fraction by giving it a denominator of 1.

If both A and B are fractions and have like denominators, multiply both fractions by the denominator to eliminate it and you are left with two whole numbers

If both A and B are fractions and have unlike denominators, find the LCD(A, B) and rewrite the fractions with the LCD as the denominator. Multiply both fractions by the denominator to eliminate it and you are left with two whole numbers

If both A and B are whole numbers, Find the greatest common factor of A and B, GCF(A, B), and divide A and B each by the GCF

Example: Simplify the ratio 6 : 10

The factors of 6 are: 1, 2, 3, 6

The factors of 10 are: 1, 2, 5, 10

Then the greatest common factor of 6 and 10 is 2

Divide both terms by 2

6 ÷ 2 = 3

10 ÷ 2 = 5

Rewrite the ratio using the results. The simplified ratio is 3 : 5.

6 : 10 = 3 : 5 in simplest form

A researcher wishes to determine whether there is a difference in the average age of middle school, high school, and college tea

MakcuM [25]

The correct statement that can be made about the means is a. There is not enough evidence to suggest that the means are different.

<h3>What is true about the means?</h3><h3 />

Given that α = 0.01, we can use an ANOVA analysis to determine the p-value of the means.

When we run the means through an ANOVA software, the p-value can be found to be 0.1142.

This figure is greater than α = 0.01.

This means that we do not have the evidence to reject the null hypothesis that the means are different.

Options for this question:

a. There is not enough evidence to suggest that the means are different.
b. The mean age of middle school teachers is different from the mean age of high school teachers.
c. The mean age of middle school teachers is different from the mean age of college teachers.
d. The mean age of high school teachers is different from the mean age of college teachers.

Which graph represents the function over the interval [−3, 3]?

rosijanka [135]

In mathematics, the functions of the whole part are functions that take a real number and return a whole number, either by excess or by default.
Function floor (or ground), that to each real number assigns the nearest whole number by defect, that is to say, the greater whole number equal or smaller than that real number.
Let's evaluate the extremes of the interval
x = -3
g (-3) = floor (-3) -2 = -5
x = 3
g (3) = floor (3) -2 = 1
Therefore, the graph that best corresponds to the function in the given interval is the attached graph.
