Answer:

Both are rational.

Step-by-step explanation:

As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.

And we know the product of two integers is an integer

p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.

Thus a+b and a-b is rational.

Ramon was studying pond life in Doyle Park. In two hours, he counted four more frogs than turtles. The number of crayfish he cou

deff fn [24]

Let us assume the number of turtles = x
Then
Number of frogs = x + 4
Number of crayfish = 2x + 3
Total number of turtles and crayfish = 54
Then we can write the equation as
x + 2x + 3 = 54
3x + 3 = 54
3x = 54 - 3
3x = 51
x = 51/3
   = 17
Then
The number of frogs = x + 4
      = 17 + 4
      = 21
So there are 21 frogs in the pond that has been counted by Ramon.
