1.the fourth multiple of 9 is divided by the second multiple of 6.find the quotient.
fourth multiplr of 9 =___________
second multiple of 6 =___________
∴the quotient =___________________=___________________
2.how many times of the H.C.F.of 24 and 36 is their L.C.M.
3.in a bakery,250 cakes and 400 bread were sold yesterday.the number of cakes sold today is decreased by 10% and that of bread is increased by 15%.find the total number of cakes and bread sold today.

1、36,12,3；2、H.C.F=12,L.C.M=72；3、250(1-10%)＋400(1＋15%)=685；4、不好意思,没怎么读懂…
我学数学还没见过这样的试题呢？头一次让我开眼界了，请教啦~~~
我只回答第四个：100%，100%+23%=123%
...这个 楼主 是要说明什么
