How much is half plus half?

This topic is about the calculation of fractional addition. When two fractions are added, their denominators should be the same. Molecules and molecules are added as molecules, so the denominator of 2 1 plus 1 remains unchanged, and the addition of molecules and molecules is 1 equal to 2, so the answer to this question is equal to 2, which is equal to 1.

1 in 2 can be understood as a thing being divided into 2. Simply put, an apple is divided into two halves, half of which is 1 of the original apple, and the two halves are combined to form 1 apple, which is 1.
