QuestionFor a field trip, the adult to student ratio is 2:9.
d) If 45 students attend, how many adults are needed? e) If 18 adults volunteer, how many students can attend? f) What two equivalent ratios to $2:9$ can you find?

Studdy Solution
For question f), we need to find two equivalent ratios to29. The ratios we found in the previous two questions are equivalent to29.
The first equivalent ratio is the ratio of adults to students when45 students attend, which is1045.
The second equivalent ratio is the ratio of adults to students when18 adults attend, which is1881.
So, the two equivalent ratios to29 are1045 and1881.
