Question

Cheddar cheese costs 7.50 for 1 kg Marie buys 200 grams of cheddar cheese how much does she pay

Answer 1

Marie would pay $1.50 because 200 grams is .2 Kg and you would multiply 7.50 by .2 and you'd get your answer

Answer 2

The correct answer is:

$1.50.

Explanation:

1 kg = 1000 g. We can set up a proportion to solve this:

7.50/1000g = x/200g

Cross multiply:

200(7.50) = x(1000)

1500 = 1000x

Divide both sides by 1000:

1500/1000 = 1000x/1000

1.50 = x
