Question

470-(500-25×3) (120-80)/(100/25) (300+160/4)/2

Answer 1

Ответ:

1) 45

2) 10

3) 170

Пошаговое объяснение:

1) 470-(500-25•3)

25•3=75

500-75=425

470-425=45

2) (120-80) : (100:25)

120-80=40

100:25=4

40:4=10

3) (300+160:4):2

160:4=40

300+40=340

340:2=170

Answer 2

Ответ:

$470 - (500 - 25 \times 3)$

$- 25 \times 3 = - 75$

$500 - 75 = 425$

$470 - 425 = 45$

(120-80)÷(100÷25)

100÷25=4

120-80=40

40÷4=10

(300+160÷4)÷2

160÷4=40

300+40=340

340÷2=170

Answer 3

Let's solve the expression step by step:

1. Start with the innermost operations within parentheses:

   • Inside the first set of parentheses: 25 × 3 = 75.
   • Inside the second set of parentheses: 120 - 80 = 40.
   • Inside the third set of parentheses: 160 / 4 = 40.

2. Now, the expression becomes: 470 - (500 - 75) (40) / (100 / 25) (300 + 40) / 2

3. Continue to simplify:

   • 500 - 75 = 425.
   • 100 / 25 = 4.
   • 300 + 40 = 340.

4. The expression now looks like this: 470 - 425 * 40 / 4 * 340 / 2

5. Perform multiplication and division from left to right:

   • 425 * 40 = 17000.
   • 17000 / 4 = 4250.
   • 4250 * 340 = 1445000.
   • 1445000 / 2 = 722500.

So, the final result of the expression is 722500.
