Estimating — Ratios

[Page 5 of 27]

Ratio problems also may allow you to establish a logical range for the correct answer and then eliminate choices outside of that range. Let's see how we would apply our estimation strategy to a ratio question.

Three donors made contributions to a certain charity in a ratio of 1 to 2 to 5. If they donated a combined total of $154, how many dollars did the donor who contributed the greatest amount give to the charity?
105
95
76
40
19
For the question above, use the values given in the stem to estimate your way to the correct answer. Fill in the Text Box below with your answer based on our new ratio, and then click Continue.

If the contributors gave equal amounts to the charity (a ratio of 1 to 1 to 1), each contributor donated approximately dollars.

 

Now, for each answer choice below, decide if it should eliminated or if it should be kept as a possible correct answer, based on how it compares to our approximation. Click Continue when you're done.
 
Eliminate
Keep
  
Choice (A): 105
 
Choice (B): 95
 
Choice (C): 76
 
Choice (D): 40
 
Choice (E): 19
