Question

Determine o valor de x:
A:5/3. x = 1
B:4/7. x = 1
C:0,75. x = 1
D:2,5. x = 1

Answer 1

$a. \\ \frac{5}{3} \times x = 1 \\ x = \frac{1}{ \frac{5}{3} } \\ x = 1 \times \frac{3}{5} \\ x = \frac{3}{5}$

$b. \\ \frac{4}{7} \times x = 1 \\ x = \frac{1}{ \frac{4}{7} } \\ x = 1 \times \frac{7}{4} \\ x = \frac{7}{4}$

$c. \\ 0.75 \times x = 1 \\ x = \frac{1}{0.75} \\ x = 1.33333...$

$d. \\ 2.5 \times x = 1 \\ x = \frac{1}{2.5} \\ x = 0.4$
