$\boxed{ \sf{1. \: \: \: \: 46.67}}$

$\boxed{ \sf{2. \: \: \: \: 41.67\%}}$

$\boxed{ \sf{3. \: \: \: \: 0.375}}$

$\boxed{ \sf{4. \: \: \: \: 120}}$

Step-by-step explanation:

1. Let the number be x

$\sf{15\% \: of \: x = 7}$

$\dashrightarrow{ \sf{ \frac{15}{100}x = 7}}$

$\dashrightarrow{ \sf{0.15x = 7}}$

$\dashrightarrow{ \sf{x = \frac{7}{0.15}}}$

$\dashrightarrow{ \sf{46.67}}$

-------------------------------------------------------------

2. Let the percent be x %

$\sf{x\% \: of \: 60 = 25}$

$\dashrightarrow{ \sf{ \frac{x}{100} \times 60 = 25}}$

$\dashrightarrow{ \sf{ \frac{60}{100}x = 25}}$

$\dashrightarrow{ \sf{0.6x = 25}}$

$\dashrightarrow{ \sf{x = \frac{25}{0.6} }}$

$\dashrightarrow{ \sf{41.67\%}}$

-----------------------------------------------------------

3. $\sf{0.15\% \: of \: 250}$

$\dashrightarrow{ \sf{ \frac{0.15}{100} \times 250}}$

$\dashrightarrow{ \sf{0.375}}$

----------------------------------------------------------

4. Let the number be x

$\sf{250\% \: of \: x = 300}$

$\dashrightarrow{ \sf{ \frac{250}{100} \times x = 300}}$

$\dashrightarrow{ \sf{2.5x = 300}}$

$\dashrightarrow{ \sf{x = \frac{300}{2.5} }}$

$\dashrightarrow{ \sf{x = 120}}$

Hope I helped!

Best regards! :D
