There are 10 fish and 5 are taken away, that means that the sum we have to do is:

10 - 5

So, 10 - 5 ≈ 5

So there are 5 fish left in the tank.

The ratio of tagged fish to untagged fish was 2 to 9. Ninety fish were tagged. How many fish were untagged

Nimfa-mama [501]

Answer:

405

Step-by-step explanation:

Since

2 : 9 = 90 : X

Then we know

9/2 = X/90

Multiplying both sides by 90 cancels on the right

90 × (9/2) = (X/90) × 90

90 × (9/2) = X

Then solving for X

X = 90 × (9/2)

X = 405

Therefore

2 : 9 = 90 : 405

14 over 15 rounded to the nearest tenth

NARA [144]

Answer:

0.9

Step-by-step explanation:

14/15 = 0.933333333 IF:

1. You first change it into a decimal by dividing the numerator by the denominator.

14 ÷ 15

2. You will get a recurring decimal.

0.933333333

3. The first digit after the decimal is in the position of the 'tenths'

0.9

4. You should use only two digits after the decimal to calculate

0.93

5. Since the number 3 is less than five, it will change into a zero and get eliminated.

∴ The answer will be = 0.9
