How is the process of finding equivalent ratios like the process of finding equivalent fractions?

Answers

Answer 1

Answer: It's generally the same, because each ratio can be written as a fraction and each fraction can be written as a ratio. For example:

1 : 2 = 1/2
5 : 7 = 5/7
3.5 : 4.3 = 3.5/4.3 = 35/43
etc.

Finding equivalent ratios is just multiplying or dividing both sides by the same number. Finding equivalent fractions is multiplying or dividing both numerator and denominator by the same number, so it's the same. For example:

1 : 2 = 2 : 4
1/2 = 2/4

5 : 7 = 10 : 14
5/7 = 10/14

3.5 : 4.3 = 7 : 8.6
35/43 = 70/86

etc.

Last year at a certain high school, there were 132 boys on the honor roll and 90 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 20%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).

Answers

The percentage of increase of total number of students on the honor roll is obtained as 22.97%.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The number of boys and girls on the honor code last year is given as 132 and 90.

Then, the total number is 132 + 90 = 222.

When, the number of boys increased by 25%, it can be obtained as,

⇒ 132 + 25% × 132 = 165

And, the number of girls increased by 20% can be obtained as,

⇒ 90 + 20% × 90 = 108

Now, the total number of students is 165 + 108 = 273.

The percent increase can be obtained as follows,

Change in the total number ÷ Initial number × 100

⇒ (273 - 222) ÷ 222 × 100 = 22.97%

Hence, the percent value of the increase in the number is 22.97%.

If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n must be _______.A. less than -10B. between -1 and -1/10C. between -1/10 and 0D. between 0 and -1/10E. greater than 10

Answers

Answer: E. Greater than 10

Step-by-step explanation:

First, know that number to the left of a number line are negative and the square of any negative number will be positive and a perfect square.

Since the square of the unknown number is less than 1/100 i.e 0.01 then the possible unknown number 'n' can be -0.01 itself, of which the square of -0.01 will give us 0.0001 (1/10,000) i.e a value less than 0.01.

The reciprocal of 1/10000 is 10,000 which is a value greater than 10.
