Draw figures to represent the number of 1/2 present in 4.
Solution
To represent the number of 21 present in 4, we can think of 4 as the sum of multiple 21 pieces. Specifically, we need to find how many 21 pieces add up to 4.
Mathematically, we can write:
4=21+21+21+21+⋯+21
Since 21 is half of 1, it takes 2 halves to make a whole number. Therefore, to make 4, we need:
4×2=8
So, there are 8 halves in 4. Let's illustrate this with figures:
Imagine each square represents 1 whole, and each half-square represents 21:
Whole Numbers Representation:
\hline
1 & 1 & 1 & 1 \\
\hline
\end{array}$$
2. **Halves Representation:**
$$\begin{array}{|c|c|c|c|c|c|c|c|}
\hline
\frac{1}{2} & \frac{1}{2} & \frac{1}{2} & \frac{1}{2} & \frac{1}{2} & \frac{1}{2} & \frac{1}{2} & \frac{1}{2} \\
\hline
\end{array}$$
So, in the second diagram, there are 8 halves. This visually represents the number of $$\frac{1}{2}$$ present in 4.
