18/20=9/10 9*10=90%
use the fraction or decimal then multiply by 100 or ten depending
Answer:
5 : 6
Step-by-step explanation:
The ratio is ...
girls : boys = 20 : 24
By removing a common factor of 4 from each of these numbers, the ratio can be reduced to lowest terms:
girls : boys = 5 : 6

Volume = LWH
15*5*3 = 15*15 = 225
Answer: The triangles are not similar.
Step-by-step explanation:
Two figures are similar simply if they have the same shape, but not necessarily the same size. In a more mathematical sense, similar figures have the same angle measures and proportionate side lengths.
<em>For reference, side lengths are proportionate when the ratios between corresponding/matching sides are the same.</em>
Since we do not have any angles, we will try using the SSS Similarity Theorem, which states that if all three sides of both triangles are in proportion, then the triangles are similar. We will first list all the side lengths and match corresponding ones.

Since we matched corresponding sides, we can now check whether they have the same ratio).


Not all of the side lengths have the same ratio, so these triangles aren't similar. you must multiply 14 by 9/7 to get to 18, but you need to multiply the other two sides by 4/3 to get to their
