Answer: " p = 6 [tex]\frac{1}{8}[/tex] " ; or, write as: " 6.125 " .

{ when "x = 7" }.

Step-by-step explanation:
p/x ;
when p = 7 ; x = 8 ;
7:8
p:x:: p:7 ;
_____________________
7:8::p:7 ; write as a "fraction:
_____________________
7/8 = p/7 ;
To find "p" when "x = 7 " ;
Cross-factor multiply:
→ that is:
→ [tex]\frac{a}{b} *\frac{c}{d}[/tex] ; ↔ ad = bc ;
_____________________________________
→ [tex]\frac{7}{8} *\frac{p}{7}[/tex] ; ↔ (7 * 7) = (8 * p) ;
→ (7 * 7) = (8 * p) ;
→ 49 = 8p ;
Divide each side of the equation by "8" ;
to isolate "p" on one side of the equation;
& to solve for "p" ;
→ 49 / 8 = 8p / 8 ;
to get:
→ 49/8 = p ;
↔ p = 48/9 ;
→ 49/8 = 49 ÷ 8 = ? ;
