There are 16 halves in 8. This is because each whole can be divided into two halves, so when you multiply 8 (the number of wholes) by 2 (the number of halves in each whole), you get 16 halves.
There are four halves in 2. This is because each whole number can be divided into two equal parts, and since 2 is a whole number, it can be divided into four halves (1/2 + 1/2 + 1/2 + 1/2 = 2).
There are five halves in 2 and a half. This is because 2 whole units contain 4 halves, and the additional half contributes one more half, totaling 5 halves.

There are two halves in a whole. If you multiply 2 by 10 you get the answer 20.
2 halves make a whole

twenty. Two halves make one whole. So in ten wholes there are 10 x 2 = 20 halves.

In one(1) whole there are two halves.(1/2 + 1/2) So in 23 whole units there will be 23 x 2 = 46 halves.
2 ÷ 1/2 = 2 x 2/1 = 4 Alternatively: 1 whole is 2 halves → 2 wholes = 2 x 2 halves = 4 halves.

2 … there are two 'halves' in a 'whole'
Two halves make up a whole. 1/2 +1/2 =1whole
