Answer:

$180lb\ 12 oz - 79.3kg = 2.8kg$

Explanation:

Given

$180\ lb 12\ oz - 79.3kg$

Required

Solve

First, convert 180lb to kg

$1lb \to 0.454kg$

$180lb \to 180 *0.454kg$

$180lb \to 81.7kg$ -- to 1dp

Next, convert 12oz to kg

$1oz \to 0.03kg$

$12oz \to 12 * 0.03kg$

$12oz \to 0.4kg$ --- to 1 dp

So, the expression becomes:

$180\ lb 12\ oz - 79.3kg$

81.7kg + 0.4kg - 79.3kg

= 2.8kg

Hence:

$180lb\ 12 oz - 79.3kg = 2.8kg$
