Answer 1

$1) : 0.5 times 45 = 22.5 \ 2) : 0.4 times 40 = 16 \ 3) : 0.2 times 9 = 1.8 \4) : 0.8 times 5 = 4 \ 5) : 0.7 times 3 = 2.1 \ 6) : 0.3 times 25 = 7.5 \ 7) : (1.7 + 2) times 4 = 3.7 times 4 = 14.8 \ 8) : (5.3 + 1.4) times 3 = 6.7 times 3 = 20.1 \ 9) : (6.15 + 3.5) times 5 = 9.65 times 5 = 48.25$
