sladkih [1.3K]

Answer:

if u have any doubts feel free to ask :)

Step-by-step explanation:

Sum of ratio : 9 + 7 + 4 = 20

a)

Adele share :

                   \frac{9}{20} \times 680 = 9 \times 34 = \$ 306

b)

Barbara share :

                    \frac{7}{20} \times 680 = 7 \times 34 =\$ 238

Collette share :

                     \frac{4}{20} \times 680 = 4 \times 34 = \$ 136

c)

    $            €

 1.125           1

 306            x

    \frac{1.125}{306} = \frac{1}{x}          [cross multiply]

x =\frac{ 306} {1.125}

x = €272

Adele receives = €272

d)

Apple        Cost

 1 kg         2.69

 5 kg          y

y = 2.69 x 5 = $13.45

Cost of 5kg of apples = $13.45

Cost of 3 kg bananas = 17.56 - 13.45 = $4.11

Banana             Cost

  3kg                 4.11

   1 kg                 z

   

  z = \frac{4.11}{3}

z = $1.37

Cost per kilogram of banana = $1.37

e) Collette share = $136

Half of it on clothes = (1/2) x 136 = $68

(1/5) of her share on books = (1/5) x 136 = 27.20

Balance amount with her = 136 - 27.20 - 68 = $ 40.80
