Problem 1: Rice Conversion

> *A bag of rice weighs 4.5 kg. If Mark uses 800 g of rice, how much rice is left in kilograms?*

Step 1: Convert grams to kilograms

We know:
> 1 kg = 1000 g

So, 800 g = 800 ÷ 1000 = 0.8 kg

Step 2: Subtract used rice from total

Total rice = 4.5 kg
Used rice = 0.8 kg
Leftover = 4.5 - 0.8 = 3.7 kg

✔ Answer: 3.7 kg

Problem 2: Ribbon Cutting

> *Sam had a ribbon that was 2.25 m long. He cut it into pieces, each 75 cm long. How many pieces did he get from the ribbon?*

Step 1: Convert meters to centimeters

We know:
> 1 m = 100 cm

So, 2.25 m = 2.25 × 100 = 225 cm

Step 2: Divide total length by piece length

Number of pieces = 225 cm ÷ 75 cm = 3

✔ Answer: 3 pieces

Problem 3: Juice Consumption

> *Mia has juice bottles that can hold 350 ml each. If she drinks one bottle daily for a week, how many liters of juice does she drink in total?*

Step 1: Find total milliliters consumed in a week

1 week = 7 days
Each day = 350 ml
Total = 7 × 350 = 2450 ml

Step 2: Convert milliliters to liters

We know:
> 1 L = 1000 mL

So, 2450 mL = 2450 ÷ 1000 = 2.45 L

✔ Answer: 2.45 liters

## ✔ Final Answers:

1. 3.7 kg
2. 3 pieces
3. 2.45 liters

These solutions involve converting between metric units (kg/g, m/cm, mL/L) and then performing basic arithmetic. Always make sure units match before adding or subtracting!
