Q2:
When positive integer x is divided by positive integer y, the remainder is 9. If x/y = 96.12, what is the value of y?
A. 96
B. 75
C. 48
D. 25
E. 12
Answer:
who can tell me how to achieve this answer?
你将x/y=96.12列个竖式就可以发现x-96y是余数,又因为x/y余数是9,所以x-96y=9。 将x=96.12y代入,得到答案。
这题在OG11的自我测试里有类似的题。
y*0.12=9
