Answer :
Sure, let's go through each part step-by-step:
1. How many centimetres are in two and a half metres?
- 1 metre is equal to 100 centimetres.
- Therefore, for 2.5 metres, you multiply 2.5 by 100.
- Calculation: [tex]\( 2.5 \times 100 = 250 \)[/tex] centimetres.
2. How many millimetres are in one and a quarter centimetres?
- 1 centimetre is equal to 10 millimetres.
- Therefore, for 1.25 centimetres, you multiply 1.25 by 10.
- Calculation: [tex]\( 1.25 \times 10 = 12.5 \)[/tex] millimetres.
3. How many metres are in five and three-quarters kilometres?
- 1 kilometre is equal to 1000 metres.
- Therefore, for 5.75 kilometres, you multiply 5.75 by 1000.
- Calculation: [tex]\( 5.75 \times 1000 = 5750 \)[/tex] metres.
4. How many kilometres are in ten thousand and sixty-five metres?
- 1000 metres is equal to 1 kilometre.
- Therefore, for 10065 metres, you divide 10065 by 1000.
- Calculation: [tex]\( \frac{10065}{1000} = 10.065 \)[/tex] kilometres.
5. How many milligrams are in one and a quarter grams?
- 1 gram is equal to 1000 milligrams.
- Therefore, for 1.25 grams, you multiply 1.25 by 1000.
- Calculation: [tex]\( 1.25 \times 1000 = 1250 \)[/tex] milligrams.
6. How many grams are in two and a fifth kilograms?
- 1 kilogram is equal to 1000 grams.
- Therefore, for 2.2 kilograms, you multiply 2.2 by 1000.
- Calculation: [tex]\( 2.2 \times 1000 = 2200 \)[/tex] grams.
7. How many kilograms are in half a tonne?
- 1 tonne is equal to 1000 kilograms.
- Therefore, for 0.5 tonne, you multiply 0.5 by 1000.
- Calculation: [tex]\( 0.5 \times 1000 = 500 \)[/tex] kilograms.
These calculations give you the answers to each of the conversion questions.
