The sharks are fed three times a day. during the morning feeding , 2/15 tons of fish is fed. during the afternoon feeding, the weight of fish fed will be 1/15 ton more than the fish fed during the morning. if the total weight of fish fed in a day is 1/2 ton, how much is fed during the feeding at night?

1/6 ton of fish is fed during the feeding at night.

Step-by-step explanation:

The fish fed in the morning is tons, and during after noon the fish fed is more than in the morning; or

and let us call the tons of fish fed at night , then if the total tons of wish fed during the is , we have

Let us add the numerators on the left side and we get:

and subtract from both side to isolate

and since , we have

the common denominator of the fractions is 6; therefore, we rewrite the equation as

and subtract the numerators to get:

which the number of tons fed during the feeding at night.

a² + b²= c²

24² + 7² = c²

c= 25
