Question

Find the value of x in the given proportions​

Answer 1

Step-by-step explanation:

$(1) \\ \frac{0.9}{0.6} = \frac{x}{3} \\ x = \frac{0.9 \times 3}{0.6} \\ x = 4.5 \\ \\ (2) \\ \frac{x}{5 } = \frac{28}{35} \\ x = \frac{28 \times 5}{35} \\ x = 4 \\ \\ (3) \\ \frac{1.6}{x} = \frac{0.12}{0.24 } \\ x = \frac{1.6 \times 0.24}{0.12} \\ x = 3.2 \\ \\ (4) \\ \frac{16}{x} = \frac{x}{25} \\ {x}^{2} = 16 \times 25 \\ {x}^{2} = 400 \\ x = 20$
