Math Problem Statement

La o grădină zoologică sunt 317 animale adulte și cu 250 mai puțini pui. Formulează întrebări astfel încât să se rezolve prin scădere sau scădere și adunare.

Solution

The text in the image describes a problem involving animals in a zoo. It states:

"There are 317 adult animals and 250 fewer young animals at a zoo. Formulate questions so that they can be solved using:

a) a subtraction; b) a subtraction and an addition."

Here is how you can create questions based on this problem:

a) Subtraction:

Question: How many young animals are in the zoo?
Solution: Subtract 250 from 317 to determine the number of young animals.
317250=67 young animals.317 - 250 = 67 \text{ young animals.}

b) Subtraction and Addition:

Question: What is the total number of animals in the zoo?
Solution: First, find the number of young animals using subtraction as above, then add the number of adult animals to the number of young animals.
317250=67(young animals)317 - 250 = 67 \quad \text{(young animals)}
317+67=384(total animals).317 + 67 = 384 \quad \text{(total animals).}

Would you like me to explore this further or provide more examples?

Expanding Questions:

  1. What percentage of the animals in the zoo are adults?
  2. If 50 young animals are added, how many young animals will there be in total?
  3. How many more adults than young animals are there in the zoo?
  4. If 10% of the adult animals leave, how many adults remain?
  5. What is the difference in the ratio of adult to young animals compared to the total number of animals?

Tip: Always start by identifying which numbers relate to which operations (addition, subtraction) to simplify problem-solving!
