Answer:

x = 25

Step-by-step explanation:

40% of something = 10.

Let something = x

40% = 40 / 100

40/100 *x = 10 Multiply by 100

40x = 10 * 100 Combine

40x = 1000 Divide by 40

x = 1000/40

x = 25

$40\% \times x = 10 \\\\\\\implies \dfrac{40}{100} x = 10\\\\\\\implies \dfrac{4x}{10} = 10\\\\\\\implies 4x = 100\\\\\implies x = \dfrac{100}4 =25$

Answer:

$\frac{16}{36} = \frac{8}{18} = \frac{4}{9}$

Step-by-step explanation:

$\frac{16}{36} = \frac{16/4.5}{36/4.5} = \frac{3.5555}{8} \neq \frac{3}{8} \\\\\frac{16}{36} = \frac{16/12}{36/12} = \frac{1.3333}{3} \neq \frac{1}{3} \\\\\frac{16}{36} = \frac{16/9}{36/9} = \frac{1.7777}{4} \neq \frac{1}{4} \\\\\frac{16}{36} = \frac{16/4}{36/4} = \frac{4}{9} \\\\\frac{16}{36} = \frac{16/7.2}{36/7.2} = \frac{2,2222}{5} \neq \frac{2}{5} \\\\\frac{16}{36} = \frac{16/2}{36/2} = \frac{8}{18} \\\\$
