Question

Resolva os problemas da regra de três simples​

Answer 1

1)

80 ----- 20

x ------ 28

20x = 80.28

20x = 2240

x = 2240/20

x = 112 voltas

2)

8 ------ 3

6 ------ x

6x = 8.3

6x = 24

x = 24/6

x = 4 dias

3)

6 ------ 8

3 ------ x

3x = 6.8

3x = 48

x = 48/3

x = 16 dias

4)

3000 ---- 6

4000 ---- x

3000x = 6.4000

3000x = 24000

x = 24000/3000

x = 8 horas

5)

4 ----- 18

9 ----- x

9x = 18.4

9x = 72

x = 72/8

x = 8 dias
