Question

At a supermarket, prawns are sold at $1.68 for every 100 g. How much does 2 kg of prawns cost? PAKE WORKING/USE WORKING

Answer 1

We need to convert kg to gram
Then use unitary method to solve it.

Calculation :
100 gm prawns costs = 1.68$
1000 gm prawns would cost = (1.68 x 10)$ = $16.8
2000 gm prawns would cost = (2 x 16.8)$ = $33.6

Since 1000gm = 1 kg
2000gm = 2kg
So, the cost for 2kg prawns = 33.6$
