Question

1. if 101.3 kpa = 14.68 psi (pounds per square inch), convert 21.1 kpa to psi. (record your answer in the numerical - response section below.)

Explanation:

Step1: Set up proportion

Let $x$ be the value in psi for $21.1$ kPa. We know that $101.3$ kPa is equivalent to $14.6$ psi. So the proportion is $\frac{101.3}{14.6}=\frac{21.1}{x}$.

Step2: Cross - multiply

$101.3x = 14.6\times21.1$.

Step3: Calculate the right - hand side

$14.6\times21.1 = 308.06$. So $101.3x=308.06$.

Step4: Solve for $x$

$x=\frac{308.06}{101.3}$.
$x = 3.041066$. Rounding to three decimal places, $x\approx3.041$.

Answer:

$3.041$
