150g of roquefort cheese cost £1.68<br> work out the cost of 250g of roquefort

mafiozo [28]

ANSWER

250g of Roquefort cheese will cost

£2.8

EXPLANATION

If 150g of roquefort cheese cost £1.68, we can write the ratio,

$150: 1.68$

Let 250g of Roquefort cheese cost £x.

Then we can again write the ratio,

$250:x$

We can equate the two ratios and solve for x.

$150: 1.68 = 250:x$

We rewrite the ratios as fractions to obtain,

$\frac{150}{1.68} = \frac{250}{x}$

We cross multiply to get,

$150x = 250 \times 1.68$
This implies that,

$150x = 420$

Divide both sides by 150 to get,

$x = \frac{420}{150}$
$x = 2.8$

Therefore 250g of Roquefort cheese will cost

£2.8
