Dean loves rocks. Altogether, they have 6 pieces of granite, 3 pieces of marble, and 14 pieces of sandstone. What is the ratio of pieces of sandstone to total pieces of rock in Dean's collection? Choose 1 answer: (A) 9:14 (B) 14:9 (C) 14:23 (D) 23:14

Finding Total Number of Rocks: First, let's find the total number of rocks in Dean's collection by adding the number of pieces of each type of rock. Total rocks = Number of granite pieces + Number of marble pieces + Number of sandstone pieces Total rocks = 6 (granite) + 3 (marble) + 14 (sandstone) Total rocks = 6 + 3 + 14 Total rocks = 23Calculating Ratio of Sandstone to Total Rocks: Next, we need to find the ratio of pieces of sandstone to the total number of rocks. We already know there are 14 pieces of sandstone and 23 total rocks. Ratio of sandstone to total rocks = Number of sandstone pieces : Total number of rocks Ratio of sandstone to total rocks = 14 : 23

Finding Total Number of Rocks: First, let's find the total number of rocks in Dean's collection by adding the number of pieces of each type of rock. $\newline$ Total rocks = Number of granite pieces + Number of marble pieces + Number of sandstone pieces $\newline$ Total rocks = $6$ (granite) + $3$ (marble) + $14$ (sandstone) $\newline$ Total rocks = $6 + 3 + 14$ $\newline$ Total rocks = $23$
Calculating Ratio of Sandstone to Total Rocks: Next, we need to find the ratio of pieces of sandstone to the total number of rocks. We already know there are $14$ pieces of sandstone and $23$ total rocks. $\newline$ Ratio of sandstone to total rocks = Number of sandstone pieces : Total number of rocks $\newline$ Ratio of sandstone to total rocks = $14 : 23$
