Question

3. If Susie drinks 2.2 l every day, how much will she drink in a fortnight?​

Answer 1

Answer:

Step-by-step explanation:

fortnight =14 days

in 1 day water she drinks = 2.2l

total water she drinks = 2.2 x 14

= 30.8l

Answer 2

1 day = 2.2 litre

fornight ( 14 days ) = ? litre

im solving this using proportion method

  DAY(x)                                   LITRE(y)

    1                                          2.2

    14                                         ?(let it be y)

this is direct proportion

then x/y = constant

1/2.2 = 14/y

using cross multiply

y = 14 × 2.2

y = 30.8 litre

OR

1 day = 2.2 litre

14 days = 2.2 × 14

            = 30.8 litre
