in a fish tank, 6/7 of the fish have a red stripe on them.if 18 of the fish have red stripes, how many total fish are in the tan

kicyunya [14]

You can solve this problem using ratios.
6/7 of the fish have a red stripe.
18 fish have a red stripe.
6:7 = 18:x
6/7 is just a simplified fraction of 18/x, both of which are equal.
In these fractions, the numerator represents the fish with red stripes and the denominator represents the total number of fish.

6:7 = 18:x
x = Total fish
The question is asking us to find x.

Since the fractions are equivalent and there is a known numerator in both of them, divide the numerator of 18:x, or 18/x, which is 18, by the numerator of 6:7, or 6/7, which is 6.
18 / 6 = 3
Now multiply 3 by the known denominator, which is 7.
7 • 3 = 21

6/7 = 6:7
18/x = 18:x
6:7 = 18:x
6:7 = 18:21
x = 21

There are 18 fish with red stripes.
There are 21 total fish.
6/7, or about 86%, of the fish have red stripes.

The answer is there is a total of 21 fish in the tank.

Hope this helps!

Answer:

<h2>There is 8% probability of Kitzen winning first and Ava second.</h2>

Step-by-step explanation:

The given table shows that there are 4 students, so there are 4 possible winner in total, but they have different number of tickets.

The total number of tickets is 48, that's the total possible outcomes. Kitzen has a probability of

$P_{Kitzen}=\frac{12}{48}=\frac{1}{4}$
