Answer 1

a) 87,23 + 15,24 = 102,47
102,47 - 13,563 = 88,907

b) 1,753 x 10 = 17,53
12,35 x 10 = 123,5
17,53 + 123,5 = 141,03

c) 2,3 x 1,2 = 2,76
2,76 + 1,4 = 4,16

d) 343,2 : 15 = 3432 : 150 = 22,88
14,7 : 2 = 147 : 2 = 73,5
22,88 + 73,5 = 96,38

Answer 2

a)87,23+15,24-13,563

=87,23+15,24=102,47

=102,47-13,563=88,907

b)1,753•100+12,35•10

=1,753•100=175,300

=12,35•10=123,5

=173,300+123,5

=296,8

c)2,3•1,2+1,4

=2,3•1,2=2,76

=2,76+1,4=4,16

=2,76+4,16

=6,92

d)343,2:15+14,7:2

=343,2:15=22,88

=14,7:2=7,35

=22,88+7,35

=30,23
