Chapter 6.4, Problem 1GP

To determine

Numbers of legs to number of spiders are in proportion.

Answer to Problem 1GP

All ratios are equal, so numbers of legs to number of spiders are in proportion.

Explanation of Solution

Given information: 

The following table that shows the ratios of number of legs to number of spiders:

  

Concept used:

Two quantities are in proportion if there ratios are equal.

Calculation:

From given table, different ratios from number of legs to number of spiders are:

  $\frac{\text{Number of legs}}{\text{Number of spiders}}=\frac{8}{1}=8=\frac{16}{2}=\frac{24}{3}=\frac{32}{4}$

Based on above calculation, as all ratios are equal to 8, these are in proportion.
