Question

For each 13 mm of coloured fabric Gordon uses to make his curtains, he also uses 1 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form.

Answer 1

For each 13 mm of coloured fabric Gordon uses to make his curtains, he also uses 1 cm of white fabric. Express the amount of white fabric to coloured fabric as a ratio in its simplest form.

answer

$1mm = \frac{1}{10} cm \\ 13mm = \frac{13}{10} cm \\ = 1.3cm$

1.3 : 1 is the ratio

Answer 2

As it is given that 13 mm of coloured cloth is used and a 1 mm of cloth is used

So to find the ratio of them we have to use the formula

$\large \sf \frac{amount \: of \: white \: cloth \: used}{amout \: of \: coloure \: cloth \: used}$

The reason why we are putting the amount of the white cloth on the numerator and the amount of colour cloth on the denominator is because....

In the question it is given that we should find the ratio of the white cloth and the black cloth,if it was inversely given ,only then we must put the amount of coloured cloth on the numerator and the white cloth on the denominator

So substituting the values,we get

$\large \sf \frac{1mm}{13mm} \\ \\ \sf{}so \: their \: ratio \: is \: \huge1 \ratio13$
