Answer 1

Se efectueaza mai intai inmultirea, apoi adunarea si scaderea
$a)3.25 \times 10 + 1.5 \times 2 = \\ = 32.5 + 3 = 35.5$
$b)4.5 \times 100 + 0.01 \times 3 = \\ = 450 + 0.03 =450.03$
$c)0.025 \times 100 + 4 \times 0.5 = \\ = 2.5 + 2 = 4.5$
$d)0.14 \times 1000 - 3.53 \times 2 = \\ = 140 - 7.06 = 132.94$
$e)5.4 \times 6.2 - 1.02 \times 10 = \\ = 33.48 - 10.2 = 23.28$
$f)5.901 \times 10 - 27.5 \times 2.6 = \\ = 59.01 - 71.5 = - 12.49$
