Question

Determine o valor de x
5/3.x=1
4/7.x=1
0,75.x=1
2,5.x=1

Answer 1

Explicação passo-a-passo:

• 5/3x = 1

x = 1 ÷ 5/3

x = 1 × 3/5

x = 3/5

• 4/7x = 1

x = 1 ÷ 4/7

x = 1 × 7/4

x = 7/4

• 0,75x = 1

75/100x = 1

x = 1 ÷ 75/100

x = 1 × 100/75

x = 100/75

• 2,5x = 1

25/10x = 1

x = 1 ÷ 25/10

x = 1 × 10/25

x = 10/25
