Word problems involving measurement conversion with illustrations of books, bananas, orange juice, and cherries.

Let’s solve each problem one by one.

Problem A:

> A box containing 4 identical books weighs 5kg. If the weight of the box is 600g, what is the weight of each book?

Step 1: Convert everything to grams for easier calculation.
5 kg = 5000 grams

Step 2: Subtract the weight of the box from total weight to get weight of all books.
5000g – 600g = 4400g (this is the weight of 4 books)

Step 3: Divide by 4 to find weight of one book.
4400 ÷ 4 = 1100 grams

✔ Each book weighs 1100 grams.

Problem B:

> I bought 10 bananas. Each banana weighed 50 grams. If the price for bananas was $6.50 per kilogram, how much did I pay?

Step 1: Find total weight in grams.
10 bananas × 50g = 500 grams

Step 2: Convert grams to kilograms.
500g = 0.5 kg

Step 3: Multiply by price per kg.
0.5 × $6.50 = $3.25

✔ You paid $3.25.

Problem C:

> Tina went to the store to buy three liters of orange juice for a party. The store only sold orange juice in 250ml cartons. How many 250ml cartons did Tina need to buy?

Step 1: Convert liters to milliliters.
3 liters = 3000 ml

Step 2: Divide total needed by size of each carton.
3000 ÷ 250 = 12

✔ Tina needs to buy 12 cartons.

Problem D:

> Sarah bought a 5kg bag of cherries at the market and ate 175g of them on the way home. How many grams of cherries did Sarah have left by the time she got home?

Step 1: Convert 5kg to grams.
5 kg = 5000 grams

Step 2: Subtract what she ate.
5000g – 175g = 4825 grams

✔ Sarah had 4825 grams left.

Final Answer:
A: 1100 grams
B: $3.25
C: 12 cartons
D: 4825 grams
