《2025年一本五年级数学苏教版暑假计算加应用题》

1. 直接写出得数。(每题 1★)
$2a + a = $3a $4a×1.5 = $6a $0.3a×0.6c = $0.18ac
$7x - x = $6x $2.4 + m + m = $2.4+2m $5.2 + (n - 3.2) = $2+n
$15a÷3 = $5a $3.4x + 6.6x = $10x $6a + 2a×2.5 = $11a
$3.6×0.7 = $2.52 $21.6 + 0.9 = $22.5 $3.4×0.6 = $2.04
$6.1×0.7 = $4.27 $2.96 - 1.8 = $1.16 $3.2×0.4 = $1.28

答案： 1.3a 6a 0.18ac 6x 2.4+2m 2+n 5a 10x 11a 2.52 22.5 2.04 4.27 1.16 1.28

2. 解方程。(每题 4★)
$5x + 2 = 17$ $x÷0.8 = 1.6$ $7x + 25 = 228$
$5x + 4.4 = 19.4$ $4x - 3×0.9 = 5.3$ $75.8 - 12x = 3.8$
$(4x - 5)×1.5 = 9$ $3(x + 12) = 102$ $(8x + 2)÷2 = 33$

答案： 2.x=3 x=1.28 x=29 x=3 x=2 x=6 x=2.75 x=22 x=8

3. 看图列方程,并求出方程的解。(每空 2★)
方程:6x+18=66 方程的解:x=8
(2)

3个x克薯片和150克薯片共1.5千克
方程:3x+150=1500 方程的解:x=450
方程:0.24×4+x=1.3 方程的解:x=0.34

答案： 3.
(1)6x 6x+18=66 x=8
(2)3x+150=1500 x=450
(3)0.24×4+x=1.3 x=0.34
