Answer:
You have given that 5/10 of the group wanted to watch the lift off.
First, simplify the fraction 5/10:
5/10 = 1/2.
So, 1/2 of the group wanted to watch the lift off.
Let's say the group consists of \( n \) pupils. Then, the number of pupils who wanted to watch the lift off is:
\[ \frac{1}{2} \times n = \frac{n}{2} \]
Therefore, the number of pupils interested in the shuttle lift off is \( \frac{n}{2} \). Let me know if you have the total number of pupils in the group (n)
