Question

determina numarul natural c stiind ca a/b=7 , c/a=5 , a-b=60 , sa se afle c

Answer 1

a/b=7 a=7b
c/a=5 c=5a
a-b=60
7b-b=60
6b=60
b=10
a=7b = 5*10=50
c= 5a= 5*50= 250

Answer 2

a/b = 7
a = 7b
a-b = 60
7b-b = 60
6b = 60
b = 60:6
b = 10
a = 7*b
a = 7*10
a = 70
c/a = 5
a = 5*a
c = 5*70
c = 350
