Question

a, 5,3 – (-5,1)+(-5,3) + 4,9;

b, (2,7 – 51,4) – (48,6 – 7,3)

c, 2,5. (-0,124) + 10, 124 . 2,5

d) B = 6,3 + (-6,3) + 4,9

e) 15,3 - 21,5 – 3. 1,5;

f) 2(42 – 2. 4,1) + 1,25: 5.

Answer 1

a: =5,3+5,1-5,3+4,9=10

b: =2,7-51,4-48,6+7,3

=10-100=-90

c: =2,5(-0,124+10,124)=2,5x10=25

d: =6,3-6,3+4.9=4,9

e: =15,3-21,5-4,5=-10,7

Answer 2

a: =5,3+5,1-5,3+4,9=10

b: =2,7-51,4-48,6+7,3

=10-100=-90

c: =2,5(-0,124+10,124)=2,5x10=25

d: =6,3-6,3+4.9=4,9

e: =15,3-21,5-4,5=-10,7
