Choose the data that you need in solving the problem

Utter the your solving strategy!

Write down the solution, explaining how have you judged !

Check if you got the correct solution and write the answer!

1. Do read the problem, slowly, carefully!

O fabrică de confecții are de lucrat o comandă de 900 de piese pentru uniforme școlare: sacouri, veste și sarafane. Sarafane s-au comandat 129 de bucăți, un număr triplu de veste, iar restul sunt sacouri. Câte sacouri s-au comandat?

3. Do repeat the problem using your own words

4. Do connections between the data in the problem !

5. Do select the data that you need to find out the solution!

6. Do tell the your solving strategy (plan) !

Before you start writing problem solving:

Developping

Keep in mind!

A garment factory has an order of 900 pieces for school uniforms: trousers, vests and skirts. Trousers were ordered 129 pairs, three times vests, and the rest are skirts. How many skirts were ordered?

A clothing factory has an order for 900 pieces of school uniforms: skirts, vests and trousers. 129 pieces of trousers were ordered, three times the number of vests, and the rest are skirts. How many skirts were ordered?

TROUSERS

VESTS ( three time number of trousers)

SKIRTS (the rest)

Example

The solving

- It ought to include the logical explanations and operations, which result from the judgment of the solution.
- Do check if you have found the correct solution!
- Don`t forget to point out the answer that you found out!

1. Determine number of the vests, namely three times of the trousers3 x 129 = 387 (vests) 2. Determine number of the skirts: 900 – 129 – 387 = = 771 – 387 = = 384 (skirts) Verification: 129 + 387 + 384 = 900Answer: 384 fuste

Drafting the solution

or

Plan and solving

1. Determine number of the vests, namely three times of the trousers: 3 x 129 = 387 (vests)

2. Determine total of the trousers and vests:129 + 387 = 516 (trousers and vests)

3. Determine number of the skirts: 900 - 516 = 384 (skirts)

Answer: 384 skirts

Verification: 129 + 387 +384 = 900 (pieces)

Bravo!

You vill be a vinner !

Do conquer other obstacles as well!

EXCELLENT!

It`s a piece of cake!!

The more you solve, the better you are!
