Answer 1

Hello!

Olive oil costs £3.50 for 1 litrehow much 200 ml of olive oil cost

Data:

1 litre = 1000 mL  

If:  

1000 mL → £ 3.50

200 mL → y  

Solving: Rule of three (directly proportional)

$\dfrac{1000}{200} = \dfrac{3.50}{y}$

Product of extremes equals product of means:

$1000*y = 3.50*200$

$1000\:y = 700$

$y = \dfrac{700\!\!\!\!\!\!\!\dfrac{\hspace{0.4cm}}{~}}{1000\!\!\!\!\!\!\!\dfrac{\hspace{0.4cm}}{~}}$

$y = 0.7\to \boxed{\boxed{y = \£\:0.7}}\end{array}}\qquad\quad\checkmark$
