12 apples weigh 2kg 500gram . How many apples weigh 15kg ?

Let's break this problem down step by step.

Step 1: Convert the given weight of apples into a consistent unit.
We are given that 12 apples weigh 2 kg 500 grams. To make calculations easier, let's convert everything into grams.

2 kg = 2000 grams.
2 kg 500 grams = 2000 grams + 500 grams = 2500 grams.
So, 12 apples weigh 2500 grams.

Step 2: Find the weight of 1 apple.
To find the weight of 1 apple, divide the total weight of 12 apples by 12: Weight of 1 apple = 2500 grams / 12 = 208.33 grams.

Step 3: Find the number of apples that weigh 15 kg.
We need to find how many apples weigh 15 kg. First, convert 15 kg into grams:

15 kg = 15000 grams.
Now, divide the total weight (15000 grams) by the weight of 1 apple (208.33 grams): Number of apples = 15000 grams / 208.33 grams ≈ 71.99 apples.

Since we can't have a fraction of an apple, we round this number to 72 apples.

Final Answer:
72 apples weigh approximately 15 kg.
