1. 直接写出得数。(每题 1★)
$9 + 0.76 = $9.76 $0.82 + 0.9 = $1.72 $5 - 0.2 - 0.4 = $4.4
$2.8 + 0.12 = $2.92 $0.85 + 0.6 = $1.45 $5.8 + 1.2 + 4.22 = $11.22
$7.08 + 6.3 = $13.38 $7.9 - 0.79 = $7.11 $1.5 - 0.9 + 0.38 = $0.98
$4.53 - 2.7 = $1.83 $8.2 + 3.35 = $11.55 $0.51 + (2 - 0.21) = $2.3
$6.07 - 3.4 = $2.67 $1.02 + 0.08 = $1.1 $9.06 + 0.94 + 4.29 = $14.29
$5.6 - 2.44 = $3.16 $0.7 + 4.26 = $4.96 $10.54 - (6.61 - 0.6) = $4.53

答案： 9.76 1.72 4.4
