Question

Sendo a = 1/2, b = 1/3 e c = ¼, determine o valor de 3.(1/a + 2/b + 3/c).

A)
50

B)
60

C)
70

D)
80

Answer 1

Explicação passo a passo:

3 ( 1/a + 2/b + 3/c )

a= 1/2

b= 1/3

c = 1/4

3 *[ ( 1/(1/2) + 2/(1/3) + 3/(1/4) ]

1 : 1/2 = 1 * 2 = 2 <<<<<

2 : 1/3 = 2 * 3 = 6 >>>>>

3: 1/4 = 3 * 4 = 12 >>>>

reescrevendo

3 * [ 2 + 6 + 12 ] =

2 + 6+ 12 =20

3 * 20 =60 >>>>> resposta >>>
