Question

Tengo que colocar paréntesis donde sea necesario par que la igualdad sea verdadera

1. 36 + 4 : 4 - 5 = 5

2. 36 + 4 : 4 - 5 = 32

3. 60 x 25 + 5 - 500 : 5 = 1.700

4. 49 + 7 : 7 - 7 = 1

5. 7 - 7 x 15 + 6 = 0

me ayudan?

Answer 1

1.
36 + 4/4 - 5 = 5
(36 + 4)/4 - 5 = 5
40/4 - 5 = 5
10 - 5 = 5

2. 
36 + 4/4 - 5 = 32
36 + (4/4) - 5 = 32
36 + 1 - 5 = 32
37 - 5 = 32

3.
60 * 25 + 5 - 500 / 5 = 1 700
60 * (25 + 5) - 500 / 5 = 1 700
60 * 30 - 100 = 1 700
1 800 - 100 = 1 700

4.
49 + 7/7 - 7 = 1
(49 + 7)/7 - 7 = 1
56/7 - 7 = 1
8 - 7 = 1

5.
7 - 7 * 15 + 6 = 0
(7 - 7) * (15 + 6) = 0
0 * 21 = 0
