65.3 million = 6530万=6.53千万 (我们一般不说653十万) 98,000 = 9.8万=9万8千 1,375,000,000 = 13.75亿=13亿7千5百万

65.3 million = 6530万？6.53千万？653十万？（六千五百三十万） 98,000 = 9.8万？9万8千？（九点八万 九万八千 都行） 1,375,000,000 = 13.75亿？13亿7千5百万？（常用13亿7千5百万 13.75亿也可以 但是不常用,我们需要转换一下才好明白）

中文数字，一般用个、十、百、千、万、亿、兆 没有什么“百万”、“十亿”这样的说法。 65.3 million=六千五百三十万（million变万，小数点向右推两位） 98,000=九点八万（从右往左数四位才是万） 1,375,000,000 = 13.75亿（三个逗号就是trillion，trillion变亿，小数点向右推一位）一般习惯13.75亿。

Usually we don‘t use the “decimal point” to express the number in Chinese ,especially in large numbers. It usually be used only in the unit below “元” which is "角/分/毛"（a fractional unit of money in China (=1/10 of a yuan or 10 fen)）。 About decimal point:100=一百，106.4=一百 零 六块/元 四毛/角/分(use in daily speaking)or106.4元（which is usually said by the sounding calculator or in writing ） Consequently,the last one of each number above is the correct one And the word "百万/千万" is usually used to discribe the approximately account of money.For intance,“This vase is worth 6 million=这个花瓶值六百万in speaking 600万in writing” 10,000=一万 100，000=十万 1000,000=百万. It looks a little bit complicated cause the "," is easer to use in English number but not in Chinese(As a Chinese I am also confused when I am learning large English number.At last I think it would be much more easier if you don't use ","or just ignore it when you are translating big numers into Chinese) For example:1,000ignore the comma 1000=1千 10000=1万 10 0000=十万 100 0000=百万 While about the other detail I agree with Clair Fang's answer (Personally thinking his is more short&clear) (｡･∀･)ﾉﾞIf U still have confuse I am happy to help~

65.3 million = 6千5百30万 98,000 = 9万8千(standard) or 9.8万 (also acceptable, if context requires comparing many different figures on the same scale of 万) 1,375,000,000 = 13亿7千5百万(standard), or 13.75亿 (similarly, it is acceptable when context requires comparing different figures on that scale)
