\bf \begin{array}{ccll}
samples&lbs\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
10&0.1\\
1000&x
\end{array}\implies \cfrac{10}{1000}=\cfrac{0.1}{x}\implies x=\cfrac{1000\cdot 0.1}{10}

you could also look at it this way, 1000 samples is really 10 * 100, or 100 times 10, if 10 weight 0.1, then 100 times that will just be 100 * 0.1.

1. Chris takes 25 minutes to replace one car tyre.
vekshin1

Chris and Jim must replace a <em>total</em> quantity of 17 tyres.

<h3>What is the minimum number of tyres to be replaced?</h3>

In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:

(25/20) · x - x ≥ 3

(5/20) · x ≥ 3

x ≥ 12

Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.
