Question

Imagine that 55% of the 800 students participate in music instead of 60%. How could

you use the idea of halves with the bar model to find 55% of 800?

Answer 1

To find 55% of 800, you calculate 50% of 800, which is 400, then find 5% by halving 10% of 800, resulting in 40, and add them together to get 440.

Step-by-step explanation:

To find 55% of 800 using the idea of halves, we can break it down using the bar model.

First, find 50% of 800, which is half of 800.

Knowing that half of 800 is 400, we can then find 5% by taking half of 10% (since 5% is half of 10%).

We calculate 10% of 800 by dividing 800 by 10, which gives us 80.

Therefore, 5% is half of 80, which is 40. Now, we add the 50% and the additional 5% together to get 55%: 400 + 40 = 440. So, 55% of 800 students is 440 students.
