$1.41 ÷ 14.1 = 0.1$
$0.91 - 0.82 = 0.09$
$6.1 × 0.8 = 4.88$
$4.93 + 2.07 = 7$
$0.68 ÷ 0.17 = 4$
$4.4 ÷ 0.11 = 40$
$10.4 - 2.7 = 7.7$
$1.6 × 0.4 = 0.64$
$0.8 × 12.5 = 10$
$1.05 + 0.85 = 1.9$
$40 × 2.5 = 100$
$0.78 - 0.29 = 0.49$
$7.6 ÷ 0.19 × 1.9 = 76$
$7.7 ÷ 0.11 + 0.66 = 70.66$
$19.3 + 21.07 = 40.37$
