Question

21 kg of bannanas cost 147. How much would 9 kg cost

Answer 1

Answer: 63

Explanation:

You can set up a proportion cost/weight=cost/weight

`(147)/(21) = (x)/(9)` Costs go on the top so x is cost for 9 kg

`x=(147*9)/(21)`

x=63

Answer 2

$63

Explanation:

First find the cost of bananas per kilogram. To find that, divide $147 by 21

147/21=7

One kilogram of bananas costs $7

Now that you know the cost per kilogram, multiply $7 by the number of kilograms asked in the question, which in this case is 9

7*9=$63

9 kilograms of bananas costs $63
