If you were asked to convert 25 kg to the unit mg, which of the following would be the first fraction used in the conversion?
one kg over ten cubed g
ten cubed g over one kg
ten cubed kg over one mg
ten cubed mg over one kg

Answer : The correct option is, one kg over ten cubed g.

Explanation :

As we are given that the 25 Kg. Now we have to convert the 25 Kg into unit of mg.

For this conversion, first we have to convert kilogram into gram and then gram into milligram.

As we know that the,

1 kilogram = 1000 gram

So, 25 kilogram = 25 × 1000 = 25000 gram

Now we have to convert gram into milligram.

As we know that the,

1 gram = 1000 milligram

So, 25000 gram = 25000 × 1000 = 25000000 milligram

Hence, the first fraction used in the conversion is, one kg over ten cubed g.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck
