Answer:
[tex]180lb\ 12 oz - 79.3kg = 2.8kg[/tex]
Step-by-step explanation:
Given
[tex]180\ lb 12\ oz - 79.3kg[/tex]
Required
Solve
First, convert 180lb to kg
[tex]1lb \to 0.454kg[/tex]
[tex]180lb \to 180 *0.454kg[/tex]
[tex]180lb \to 81.7kg[/tex] -- to 1dp
Next, convert 12oz to kg
[tex]1oz \to 0.03kg[/tex]
[tex]12oz \to 12 * 0.03kg[/tex]
[tex]12oz \to 0.4kg[/tex] --- to 1 dp
So, the expression becomes:
[tex]180\ lb 12\ oz - 79.3kg[/tex]
[tex]81.7kg + 0.4kg - 79.3kg[/tex]
[tex]= 2.8kg[/tex]
Hence:
[tex]180lb\ 12 oz - 79.3kg = 2.8kg[/tex]
