Question

a si b invers proportionale cu 5 si 6 ... b.cel mai mic este 24 c.suma lor este 66 d.diferenta lor este 9

Answer 1

a/1/5 = b/1/6 => 5a= 6b

b) a = 24
5×24 = 6b
b= 5× 4
b= 20

c) a+b = 66
5a= 6b => a= 6b/5
6b/5+b = 66 |×5
6b+5b = 330
11b = 330 |:11
b = 30
a = 66-30
a = 36

d) a-b = 9
5a=6b => a = 6b/5
6b/5-b = 9 |×5
6b - 5b = 45
b = 45
a = 9+45 = 54

Answer 2

a/1/5=b/1/6 --> 5a=6b

b)
a=24
5×24=6b
b=20 (5×4)

c)
a+b=66
5a=6b-->a=6b/5
6b/5+b=66
11b=330 (66×5)
b=30 (330:11)
a=36 (66-30)

d)
a-b=9
5a=6b-->a=6b/5
6b/5-b=9
6b-5b=45 (9×5)
b=45
a=54 (9+45)
