Question

when determining soil texture, the percentages of the three soil particle types add up to 100%. if a soil had 50% sand and 50% silt, what would be the percentage of clay?
50%
0%
100%

Explanation:

Step1: Set up the equation

Let the percentage of clay be $x$. We know that the sum of the percentages of sand, silt and clay is 100%. Given sand is 50% and silt is 50%, so $50 + 50+x=100$.

Step2: Solve for $x$

$100 + x=100$, then $x = 100 - 100=0$. So the percentage of clay is 0%.

Answer:

B. 0%
