Question

REALLY URGENT

There are two types of fish in a lake. These are carp and pike.
In a netted area of the lake 120 carp and 16 pike were caught
In the whole lake it is estimated there are 34 000 fish
Zalika estimated that there are 4000 pike in the lake altogether.
How does Zalika work out this estimate.​

Answer 1

Answer: Ratios

Explanation:

Zalika can work out this estimate by using the ratio of carp to pike that she first caught. This is how to use the ratios:

1) 120 carp : 16 pike --> from given information

2) 136 fish : 16 pike --> add the numbers together to get total fish compared to pike

3) Multiply by 250 --> 34000 divided by 136 is 250

4) 34000 fish : 4000 pike --> 16x250=4000
