Answer:
[tex] \boxed{ \sf{1. \: \: \: \: 46.67}}[/tex]
[tex] \boxed{ \sf{2. \: \: \: \: 41.67\%}}[/tex]
[tex] \boxed{ \sf{3. \: \: \: \: 0.375}}[/tex]
[tex] \boxed{ \sf{4. \: \: \: \: 120}}[/tex]
Step-by-step explanation:
1. Let the number be x
[tex] \sf{15\% \: of \: x = 7}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{15}{100}x = 7}} [/tex]
[tex] \dashrightarrow{ \sf{0.15x = 7}}[/tex]
[tex] \dashrightarrow{ \sf{x = \frac{7}{0.15}}}[/tex]
[tex] \dashrightarrow{ \sf{46.67}}[/tex]
-------------------------------------------------------------
2. Let the percent be x %
[tex] \sf{x\% \: of \: 60 = 25}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{x}{100} \times 60 = 25}}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{60}{100}x = 25}} [/tex]
[tex] \dashrightarrow{ \sf{0.6x = 25}}[/tex]
[tex] \dashrightarrow{ \sf{x = \frac{25}{0.6} }}[/tex]
[tex] \dashrightarrow{ \sf{41.67\%}}[/tex]
-----------------------------------------------------------
3. [tex] \sf{0.15\% \: of \: 250}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{0.15}{100} \times 250}}[/tex]
[tex] \dashrightarrow{ \sf{0.375}}[/tex]
----------------------------------------------------------
4. Let the number be x
[tex] \sf{250\% \: of \: x = 300}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{250}{100} \times x = 300}}[/tex]
[tex] \dashrightarrow{ \sf{2.5x = 300}}[/tex]
[tex] \dashrightarrow{ \sf{x = \frac{300}{2.5} }}[/tex]
[tex] \dashrightarrow{ \sf{x = 120}}[/tex]
Hope I helped!
Best regards! :D
