Question

? write down in mm and cm and then in m

Answer 1

To find the total amount of string you bought, you can simply add the two lengths together:

\[ 4600 , \text{mm} + 2800 , \text{mm} = 7400 , \text{mm} \]

Now let's convert this total into centimeters and meters:

1. To convert millimeters to centimeters, divide by 10: \[ 7400 , \text{mm} \div 10 = 740 , \text{cm} \]

2. To convert millimeters to meters, divide by 1000: \[ 7400 , \text{mm} \div 1000 = 7.4 , \text{m} \]

So, the total amount of string you bought is:

• 7400 mm
• 740 cm
• 7.4 m
