Question

[(b: 5+3): 6] x 4 = 12

a) 3
b) 70
c) 5
d)75​

Answer 1

[(b : 5 + 3) : 6] × 4 = 12

(b : 5 + 3) = 12 : 4

(b : 5 + 3) : 6 = 3

b : 5 + 3 = 3 × 6

b : 5 + 3 = 18

b : 5 = 18 - 3

b : 5 = 15

b = 15 × 5

b = 75 ⇒ D.

Answer 2

Răspuns:

[(b:5+3):6]x4=12

(b:5+3):6=12:4

(b:5+3):6=3

b:5+3=3×6

b:5+3=18

b:5=18-3

b:5=15

b=15×5

b=75
