Question

use the given equivalents, along with dimensional analysis, to convert the given unit to the unit indicated.20 oz to g16 oz = 1 lb2000 lb = 1 t1 oz ≈ 28 g1 lb ≈ 0.45 kg1 t ≈ 0.9 t20 oz = 350 g

Explanation:

Step1: Convert ounces to pounds

Since \(16\ oz = 1\ lb\), then \(20\ oz=\frac{20}{16}\ lb = 1.25\ lb\)

Step2: Convert pounds to grams

Given \(1\ lb\approx0.45\ kg\), so \(1.25\ lb = 1.25\times0.45\ kg=0.5625\ kg\)
Since \(1\ kg = 1000\ g\), then \(0.5625\ kg=0.5625\times1000\ g = 562.5\ g\)

Answer:

\(562.5\)
