Can I add together different unit of measurement for volume?
100ml + 0.2L + 650 ml =
1. The first thing I notice is that the measurements are in different units for volume (millilitres and Litres)
I cannot add them together as they are because they are not all the same unit of measurement
100ml + 0.2L + 650 ml =
2. First choose which measurement that you will convert. In this case I will convert ‘0.2L’ into Millilitres because the other two are already measured in millilitres, which means I will have to convert less numbers.
100ml + 0.2L + 650 ml =
0.2L x 1000 =
3. I know that to convert litres to millilitres I have to multiply the number by 1000 (x1000) therefore I need to multiply 0.2 by 1000 (0.2 x 1000).
4. I could use a calculator for this calculation but I am going to use my knowledge of the place value chart because we are multiplying by 1000. When a number is multiplied by 1000 it moves three columns to left.
.
100ml + 0.2L + 650 ml =
0.2L x 1000 = 200ml
5. So if we multiply 0.2 by 1000 we get 200. Remember to write in the unit of measurement that we have converted to (Millilitres)
100ml + 0.2L + 650 ml =
0.2L x 1000 = 200ml
100ml + 200ml + 650 ml =
6. Next we rewrite the calculation again but this time we replace the 0.2L with 200ml. Now we add up all the numbers in the calculation like any other addition problem. You could solve it mentally or you could use a written method like column method:
H T U
1 0 0
2 0 0
+ 6 5 0
9 5 0
7. And the final step: Write your answer into the calculation. Remember to write the unit of measurement (millilitres):
100ml + 0.2L + 650 ml =
0.2L x 1000 = 200ml
100ml + 200ml + 650 ml = 950ml
100ml + 0.2L + 650 ml =
