NO. 18/20 is not proportional to 34/40. 18/20 : 34/40 by cross multiplication 18 * 40 = 20 * 34 720 ≠ 680 thus 18/20 is not proportional to 34/40

To divide 540 into parts proportional to 18, we first determine the total number of parts: 18 can be considered as one part. Therefore, we have 540 divided by 18, which equals 30. Thus, the parts are 30 × 1 = 30 for each unit of 18. So, the division results in 30 parts, all equal to 30.

we can cross multiply the two equivalent equations and then find the fourth proportional
NO. 18/20 is not proportional to 34/40. 18/20 : 34/40 by cross multiplication 18 * 40 = 20 * 34 720 ≠ 680 thus 18/20 is not proportional to 34/40
yes, they are.
One fourth of 18 is 18 divided by four, which is 9/2 or 4.5.

A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature. The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
Yes
Oh, what a lovely question! To find out if two ratios are proportional, we can cross multiply and see if the results are equal. So, for 8 to 9 and 18 to 16, when we cross multiply (8 x 16 and 9 x 18), we see that they are not equal. That means these ratios are not proportional, but it's all part of the happy little journey of learning!
