Question

si el 25 % de R es igual a M , ¿que tanto por ciento de (R + M)
es (R - M)?

Answer 1

Recordemos que:

25% = 0.25

Osea que:

0.25R = M

(R + M) =  (R + 0.25R) = 1.25R

R + M = 1.25M

(R - M) = (R - 0.25R) = 0.75R

Regla de 3:

100% ========> 1.25R

  X ==========> 0.75R

X = [(100%)(0.75R)]/[1.25R]

X = [(0.75)/(1.25)]*100%

X = (0.6)*100%

X = 60%

Rta: (R - M) representa el 60% de (R + M)
