Question

h➗40=0.55％,怎么算h等于多少？

Answer 1

解：解方程，h等于11/50，【即等于0.22】
h ÷ 40 = 百分之0.55
h ÷ 40 = 0.55 ÷ 100
h ÷ 40 = 55/100 × 1/100
h ÷ 40 = 11/20 × 1/100
h ÷ 40 = 11/2000
h = 11/2000 × 40
h = 11/50
∴h = 0.22
答：h等于11/50，【即等于0.22】

Answer 2

如图所示。

Answer 3

h➗40=0.55％
h=0.55％　X40
h=22

Answer 4

h÷40=0.55
解:h÷40×40=0.55×40→两边同时乘法40
h=22

追答

0.55%=0.055
h÷40=0.055
h=0.55×40
h=2.2

Answer 5

两边乘以40得
h=0.55%×40
=0.0055×40
=0.22
