Question

Расставить правильно скобки: 600-240:3+1=521, 600-240:3+1=121, 600-240:3+1=540, 600-240:3+1=90, 600-240:3+1=519, 720:9*20+60=64, 720:9*20+60=6400, 720:9*20+60=3, 720:9*20+60=1. Помогите плиз мне очень надо!

Answer 1

600-240:3+1=521;(600-240):3+1=121;600-240:(3+1)=540;(600-240):(3+1)=90;600-(240:3+1)=519
720:(9*20)+60=64;(720:9)*(20+60)=6400

Answer 2

Solving the Equation

To solve the given equation and place the brackets correctly, let's break it down step by step.

Step 1: First, let's solve the division and addition part of the equation: - 600 - 240 ÷ 3 + 1

Step 2: Now, let's solve the multiplication and addition part of the equation: - 720 ÷ 9 * 20 + 60

Correctly Placing the Brackets

Now, let's place the brackets correctly to solve the equation.

Step 1: - For the expression 600 - 240 ÷ 3 + 1: - 600 - (240 ÷ 3) + 1 = 600 - 80 + 1 = 521 - Result: 521

Step 2: - For the expression 720 ÷ 9 * 20 + 60: - (720 ÷ 9) * 20 + 60 = 80 * 20 + 60 = 1600 + 60 = 1660 - Result: 1660

Conclusion

The correctly placed brackets for the given expressions are: - 600 - 240 ÷ 3 + 1 = 521 - 720 ÷ 9 * 20 + 60 = 1660
