A RNA copy of a DNA gene is called as messenger RNA or mRNA. mRna is used in translation because information is translated from one language (nucleotides) into another (amino acids).

Hence, mRNA is used to transfer genetic information by a cell.

Expressing 3/8 as a decimal fraction:

We can convert 3/8 into a decimal fraction by just dividing 3 by 8 or making 3 into 8 parts.

Then, it is 3/8 = 0.375 as a decimal fraction.

Other Method::

3/8 as a Decimal :

In this we should convert the denominator into 10, 100, 1000, 10000, 100000,... to make it simple.

Now to make 8 into 1000, we multiply numerator and denominator with 125

=> (3 x 125)/(8 x 125) = 375/1000 = 0.375.

This can be solved in two ways using only 6, 11, 9 and 3 we must get 24.

1. {[(11–6) x 3] + 9}

By solving this we get

5 x 3 + 9 = 15 + 9 = 24.

2. [(9–6) x (11–3)]

= 3 x 8 = 24.

A mountain is what has roots that nobody sees, Is taller than trees, Up, up it goes, Yet it never grows.

In general, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
As water molecules are polar, polar molecules dissolves in water.
