Can someone please help me with the last three?? I don’t know what I keep doing wrong.

1. 78.22%

3. 21.77%

Step-by-step explanation:

To find the percentage, you multiply the fraction of those tested positive/negative (based on the question) out of the total by 100%.

1. × 100% = 78.22% (2 d.p.)

2. × 100% = 0.342% (3 d.p.)

3. × 100% = 21.77% (2 d.p.)
