《2025年阳光同学暑假口算五升六数学》

1. 直接写出得数。
$0.6 + 1.24 = $ $0.72 - 0.36 = $ $1.25×(0.4 + 0.4) = $
$1÷0.05 = $ $0.08÷0.2 = $ $6.5 + (7.8 + 3.5) = $
$10 - 2.05 = $ $0.4×0.4 = $ $9.63×101 - 9.63 = $
$6.8×5 = $ $0.58 + 4.72 = $ $1÷0.125 - 0.875 = $
$0.27 - 0.14 = $ $7.08 - 6.39 = $ $1.25÷0.25×4 = $
$0.44÷0.2 = $ $3.5×0.2 = $ $0.5×0.4 + 0.32 = $
$1.75 + 0.5 = $ $2.4÷5 = $ $4.9 + 8.7 + 5.1 = $

答案： 1.84 0.36 1 20 0.4 17.8 7.95 0.16 963 34 5.3 7.125 0.13 0.69 20 2.2 0.7 0.52 2.25 0.48 18.7

2. 计算下面各题,怎样简便就怎样算。
$9.9×4.2 + 0.42$ $7.2 + 1.25×7.2×8$ $(10.12 - 5.68)÷0.25÷0.4$
$(12.5 - 0.05)×8 - 0.6$ $12.54 - 4.56 - 3.44 - 1.54$ $5.33×101$
$15.52 - 1.6×5 - 5.52$ $0.25×4.78×8$ $3.7÷4 + 6.3×0.25$

答案： 42 79.2 44.4 99 3 538.33 2 9.56 2.5
