You convert to a larger unit. Smaller to larger. Metre is 1000 times larger than a millimetre
The answer to that one is going to depend on two things:-- what unit you are converting from-- what unit you are converting to
Move the decimal point (after 2) 3 spots to the left. remember, since you are converting from smaller to larger, the decimal point moves to the left.
Yes. For example, 100 grams = 0.1 kilograms
if the decimal number is smaller than the decimal is larger.
That depends on what you are converting from. If you are converting from larger units, you multiply. If you are converting from smaller units, you divide.
Multiply
It could be either, depending on whether you're converting to a larger or smaller unit.
Since there are 100 cm in 1 m, you must divide 12 by 100. This gives you 12/100, which can be reduced to 3/25, or 0.12 in decimal form. Whenever you are converting in metric units, you only have to move the decimal based on the different measurements. In this case, a meter is 100 centimeters, so the decimal is moved two places over. Which direction you move it depends on which way you are converting. Converting from a smaller size to a bigger one requires you to move the decimal to the left, and converting from a larger size to a smaller one requires you to move the decimal to the right, adding zeroes as necessary.
No.
You record the temperatures as decimal numbers and subtract the smaller from the larger.
16.1 is larger cause if the 1 is in the tenths then it has a larger value and 2 which is in the hundredths is a smaller value remember tenths are larger behind the decimal and more than tenths is a smaller value behind the decimal
