Utilizando a Regra de Três:

a) 15% de 250000

250000---------------100%

x-------------------------15%

100x = 250000 . 15

100x = 3750000

x = 3750000:100

x = 37500

b) 35% de 315550

315550----------------100%

x-------------------------35%

100x = 315550 . 35

100x = 11044250

x = 11044250:100

x = 110442,5
