Question

Для изготовления украшения из бисера Галина подготовила 250 штук зеленого бисера, желтого - на 70 штук больше, чем зеленого, а оранжевого - на 150 штук меньше, чем зеленого и желтого вместе. Сколько всего бисера подготовила Галина?

Answer 1

250 + 250 + 70 + 250 + 70 - 150 = 740 штук

Answer 2

1) 250+70=320 (штук) - желтого бисера.

2) 250+320=570 (штук) - зеленого и желтого вместе.

3) 570-150=420 (штук) - орнджевого бисера.

4) 570+420=990 (штук) - всего бисера.

Ответ: 990 штук бисера подготовила Галина

Answer 3

Calculating the Total Beads Prepared by Galina

To calculate the total number of beads prepared by Galina, we can use the information provided about the quantities of different colored beads.

Galina prepared: - 250 green beads - 70 more yellow beads than green beads - 150 fewer orange beads than the combined quantity of green and yellow beads

Let's calculate the total number of beads prepared by Galina step by step.

1. Calculate the Quantity of Yellow Beads - Galina prepared 70 more yellow beads than green beads. - Total yellow beads = 250 (green beads) + 70 - Total yellow beads = 320

2. Calculate the Quantity of Orange Beads - Galina prepared 150 fewer orange beads than the combined quantity of green and yellow beads. - Total green and yellow beads = 250 (green beads) + 320 (yellow beads) - Total green and yellow beads = 570 - Total orange beads = 570 - 150 - Total orange beads = 420

3. Calculate the Total Quantity of Beads - Total beads prepared = 250 (green beads) + 320 (yellow beads) + 420 (orange beads) - Total beads prepared = 990

So, Galina prepared a total of 990 beads.

Answer

Galina prepared a total of 990 beads.
