Question

180 lb 12 oz - 79.3 kg = ___________ kg

Answer 1

`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`
