2025年一本暑假计算加应用题四年级数学人教版浙江专版第40页答案
1. 直接写出得数。(每题 1★)
$8.2 + 6.5 = $ $3.72 + 1.24 = $ $6.62 - 1.4 = $
$3.7 - 2.4 = $ $6.87 - 2.94 = $ $0.35 + 0.52 = $
$1.62 + 0.5 = $ $7.26 - 0.05 = $ $0.36 - 0.05 = $
$1.3 + 5.28 = $ $7.46 + 1.9 = $ $14.76 - 4.6 = $
$5.52 + 3.2 = $ $0.36 + 0.9 = $ $6.83 - 1.22 = $

答案

14.7   4.96   5.22

2. 列竖式计算,带 * 的要验算。(每题 4★)
$0.75 + 0.86 = $ *$7.14 - 3.06 = $
$60 - 17.36 = $ *$4.7 + 5.62 = $
验算:
$16.94 + 7.62 = $ *$29.7 - 16.28 = $
验算:
