## What are the differences between ratio proportion and percentage?

Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.

## What is the mean proportion of 36 and 16?

Answer. The mean proportion of 36 and 16: 36 * 16 = 576. Sqrt of 576 = 24. So, 24 is the mean proportion of 36 and 16.

## What is the mean proportion of 9 and 16?

12

## What is the ratio of 72 Kilometre to 60 Kilometre?

Thus, the reduced form of 72 : 60 is 6 : 5.

## What is the mean proportional of 9 and 4?

6

## How do you find the mean proportion of 4 and 25?

- answer :- The mean proportional of 4 and 25 is 10.
- We know a=4 and c=25So we have :-
- B² = ac.
- :- B² = 4×25.
- :- B² = 100.
- :- B = √100.
- :- B = 10.
- so, value of B is 10.

## What is the mean proportional of 4 and 16?

## What is the mean proportion of 36 and 49?

Mean proportional =6×7=42.

## What number has to be added to each term of 3 ratio 5 to make the ratio 5 ratio 6?

Therefore, (3 + x) / (5 + x) = 5/6. On solving, we get, (3 + x) 6 = 5 (5 + x). This implies, 18 + 6x = 25 + 5x, => 6x – 5x = 25 – 18. Therefore, number to be added = x = 7.

## Which of the following set of three numbers are in continued proportion?

## Are the numbers 25 45 and 81 in continued proportion?

Yes, the numbers are in continued proportion.

## Which of the following sets of numbers are in proportion?

Hence, 2,3,6 and 9 are in proportion.

## How do you find the mean of two proportions?
