(9,9-5,52:0,69+8,1)*((5-0,125):(3,7+0,05))=

Compute step by step (using comma as decimal separator and colon as division):

• (9,9 - 5,52:0,69 + 8,1) = 9,9 - (5,52/0,69) + 8,1

  • 5,52/0,69 = 8
  • => 9,9 - 8 + 8,1 = 10

• (5 - 0,125) : (3,7 + 0,05) = (4,875) / (3,75) = 1,3

Product: 10 * 1,3 = 13

Answer: 13
