Finding the Mass of Three Perch

To find the mass of all three perch, let's break down the information provided:

- The mass of the first perch is 400 grams. - The mass of the second perch is 60 grams more than the first perch. - The mass of the third perch is half the total mass of the first two perch.

Let's calculate the mass of the second perch and the total mass of all three perch step by step.

1. Calculate the mass of the second perch: - The mass of the second perch is 60 grams more than the first perch. - Therefore, the mass of the second perch is 400 grams + 60 grams = 460 grams.

2. Calculate the total mass of the first two perch: - The total mass of the first two perch is the sum of their individual masses. - Therefore, the total mass of the first two perch is 400 grams + 460 grams = 860 grams.

3. Calculate the mass of the third perch: - The mass of the third perch is half the total mass of the first two perch. - Therefore, the mass of the third perch is 860 grams / 2 = 430 grams.

4. Calculate the total mass of all three perch: - The total mass of all three perch is the sum of their individual masses. - Therefore, the total mass of all three perch is 400 grams + 460 grams + 430 grams = 1290 grams.

Therefore, the mass of all three perch is 1290 grams.
