# Are 15 45 40 and 120 in proportion yes or no? ### Are 15 45 40 and 120 in proportion yes or no?

Hence, 15, 45, 40, 120 are not proportion.

### Are the ratios 25 30 40 48 in proportions?

Therefore, the ratios \[25g:30g\] and \[40g:48g\] are in proportion.

### Are 16 8 and 4 in continued proportions?

They are in continued prportion.

### How do you find the continued proportion?

Two ratios a: b and b: c is said to be in continued proportion if a: b = b: c. In this case, the term c is called the third proportion of a and b whereas b is called the mean proportion of between the terms a and c. Find out if the following ratios are in proportion: 8:10 and 12:15.

### Are the numbers 15 45 40120 In proportion?

15, 45, 40 and 120 are in proportion.

### How do you know if a number is in proportion?

Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.

### Which of these are middle terms if the following ratios 25 30 :: 40 48 are in proportion?

So, 25: 30 = 40: 48. The middle terms in this are 30, 40 and the extreme terms are 25, 48.

### What are the first and fourth terms of a proportion?

the extremes of The first and fourth terms are called the extremes of the proportion. The second and third terms are called the means of the proportion. the terms a and d are the extremes; the terms b and c are the means.

### Are 2 12 and 72 continued proportions?

∴ They are continued Proportion.

### What is continued proportion example?

i.e. in a : b = b : c; c is the third proportional to a and b. For example, let us consider the numbers 6, 12, 24. Thus, 6, 12, 24 are in continued proportion. The second quantity 12 is the mean proportional and third quantity 24 is the third proportional.
