Answer:

1. 43.75%

2. 60%

3. 11/20

4. 2 and 12/25

5. 0.031%

6. 600.5%

7. 3/25

8. $5.50

Explanation:

1. 7 ÷ 16 = 0.4375

0.4375 x 100 = 43.75%

2. 3 ÷ 5 = 0.6

0.6 x 100 = 60%

3. 55/100

11x25 / 20x5 = 11/20

4.248/100

62x4 / 25x4

62/25

62/25 = 2R12

2 12/25

5. 0.00031 x 100 = 0.031%

6. 6.005 x 100 = 600.5%

7. 12% = 12/100.

12/100 simplified = 3/25

8. $27.50 x 20% = $5.50

Answer:

1. 7/16 = 43.75%

2. 4/5 = 80%

3. 55% = 55/100 = 11/20

4. 248% = 2 48/100 = 2 12/25

5. 0.00031 = 0.031%

6. 6.005 = 600.5%

7. 12% = 12/100 = 3/25 (Gigi spent 3/25 of her birthday money on the new sunglasses)

8. The total bill for pizza and soft drinks was $27.50. With a 20% tip, the amount of tip left would be:

Tip = 20% of total bill

Tip = 20/100 * $27.50

Tip = $5.50

Therefore, Veronica and her friends left a $5.50 tip for their server.
