a bag of rice is having a mass os 200g costs 40p. Find the price per kilogram
40p/0.2kg = 200 p/kg
A bag of rice having a mass of 200g costs 40p .find the price per kilogram
To find the price per kilogram, we need to convert the mass of rice from grams to kilograms.
1 kilogram (kg) = 1000 grams (g)
Given that the mass of the rice is 200 grams (g), we can convert this to kilograms by dividing by 1000:
200 g ÷ 1000 = 0.2 kg
Now, let's find the price per kilogram by dividing the cost by the mass in kilograms:
Price per kilogram = Cost ÷ Mass in kilograms
Price per kilogram = 40p ÷ 0.2 kg
Price per kilogram = 200p/kg
Therefore, the price per kilogram of rice is 200 pence per kilogram.
To find the price per kilogram, we need to convert the mass and the price from grams to kilograms.
Step 1: Convert the mass from grams to kilograms.
We divide the mass of the rice by 1000 since there are 1000 grams in a kilogram.
200 g ÷ 1000 = 0.2 kg
Step 2: Calculate the price per kilogram.
We divide the cost of the rice by the mass in kilograms.
40 pence ÷ 0.2 kg = 200 pence per kilogram
To convert the price from pence to pounds, we divide by 100 since there are 100 pence in a pound.
200 pence ÷ 100 = £2 per kilogram
Therefore, the price per kilogram of rice is £2.
