The diameter of the sun is about 14 million kilometers, which is 1.26 million kilometers more than 100 times the diameter of the earth. How many thousands of kilometers is the diameter of the earth? (solution by equation)
太阳的直径约是1400万千米，比地球直径的100倍多126万千米，地球的直径是多少万千米？(用方程解)
<gadget id="calculator">1_400 - 126</gadget>
<output>1_274</output>

<gadget id="calculator">1_274 / 100</gadget>
<output>637/50 = around 12.74</output>

<result>637/50 = around 12.74</result>
