### 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.
