Answer 2

Answer:

12.50 metres and 3850 grams

Step-by-step explanation:

7. 7m 50cm + 500cm

First you change 7 metres to centimetres you do that by multiplying it by 100 which will give you

700cm 50cm +500cm

Next you add 700cm + 50cm which will give you 750cm so

750cm +500cm

Then you do 750cm + 500cm

 750cm

+500cm

 1250cm

Finally we change centimetres to metres by dividing it by 100 which will give you

12.50 metres

8. 2kg, 270g and 580g

First you change 2kilograms to grams by multiplying by 1000 which will give you

2000g, 270g, 580g

Next you add 2000g, 270g and 580 which will go like this

2000g

+270g

+580g

3850g

So your answer is 3850 grams.
