Step 1: Do the most inner parenthesis (7-2+3) = 5 + 3 = 8.

Step 2: Do the next parenthesis (14-8) = 6

23+8-6

23+8 = 31

For their history project, students case to either write a report or give a presentation. Two fifth of the students wrote a repo
Gnesinka [82]

Answer: Yes. Dominic is correct

Step-by-step explanation:

We are informed that Two fifth of the students wrote a report. This also means that (2/5 × 100) = 40% = 0.4 wrote a report and 0.6 of the students gave a presentation.

From the decimals gotten, we can see that 0.6 is more than 0.4. Therefore, more students gave a presentation. This implies that Dominic is correct.
