Sure, let's break down the solution step-by-step.
1. Understand the problem: We need to calculate the price per kilogram of black pomfret given that 400 grams are sold at RM9.40.
2. Convert the weight from grams to kilograms:
- Since there are 1000 grams in a kilogram, we convert 400 grams to kilograms by dividing by 1000.
- So, [tex]\( \text{weight in kilograms} = \frac{400 \text{ grams}}{1000} \)[/tex]
- Simplifying this, we get [tex]\( \text{weight in kilograms} = 0.4 \)[/tex] kg.
3. Calculate the price per kilogram:
- We know the total price for 0.4 kg is RM9.40.
- To find the price per kilogram, we divide the total price by the weight in kilograms.
- So, [tex]\( \text{price per kilogram} = \frac{\text{total price}}{\text{weight in kilograms}} = \frac{9.40 \text{ RM}}{0.4 \text{ kg}} \)[/tex]
- When we perform this division, we get [tex]\( \text{price per kilogram} = 23.5 \text{ RM/kg} \)[/tex].
So, the price of the black pomfret per kilogram is RM23.50.
