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.

One possible answer comes to mind - It is inconvenient if you are converting to English measurements. I'll try to think of another one but nothing so far.

Fractional part of a mixed decimal.

In decimal form, 90% is .90. This is because when converting a decimal into a percent, you move the decimal point 2 places to the right, which is the same as multiplying that decimal by 100. You multiply it by 100 because you are converting that decimal into a fraction that will represent a percentage of a full 100%.

the decimal is moved to right three times.

When converting a percent to a decimal you don't necessarily move the decimal point. It has nothing to do with it.
