请问如何计算股票的dividend and franking?

smh

看了2个股票的剖析表述，一个是MYR, 一个是LEI

MYR: dividend per share is 17 cents, it will  be trading on a
yield of 5.9%

fully franked

LEI: dividend per share is 96 cents,  it’s currently trading on a
yield of 5.8%
with
a 50% franking
.


请问外面的yield 是否红利除以估价？ 而franked/franking 如何了解？fully or 50%如何计算？
