Question

5 x 1/2
use repeated addition to find the answer

Answer 1

To solve \(5 \times \frac{1}{2}\) using repeated addition, you can think of multiplying by a fraction as adding that fraction together multiple times.

So, \(5 \times \frac{1}{2}\) means you add \(\frac{1}{2}\) a total of 5 times:

\[
\frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2}
\]

Now let's add them together:

1. \(\frac{1}{2} + \frac{1}{2} = 1\)
2. \(1 + \frac{1}{2} = 1 + \frac{1}{2} = \frac{3}{2}\)
3. \(\frac{3}{2} + \frac{1}{2} = \frac{4}{2} = 2\)
4. \(2 + \frac{1}{2} = 2 + \frac{1}{2} = \frac{5}{2}\)

So, the total sum is \(\frac{5}{2}\).

Thus, \(5 \times \frac{1}{2} = \frac{5}{2} = 2.5\).
