Answer 1

I wish authors would phrase those kind of questions in a more direct way.
e.g.
350 is 70% of what number?
-----> 70% of what number is 350 ----> .7x = 350
x = 350/.7 = 500

check: .7(500) = 350

What percent of 64 is 24? ----> (x/100)(64) = 24
x = (24/64)(100)%

The next one just like the above

last one:
20% of 140 is what number?
---> what is 20% of 140
= .2(140) = ....
