Yes
Some can, others can't.
Fractions and decimals are a major part of mathematics, and mathematics is a major part of engineering. They are used for a huge range of things involved in calculations for almost every part of an engineer's job.
Of course, there isn't a reason not to, because mathematics is the language of economics, science and engineering(with the exception of computer programming).

Highly possible, math is more important than writing.
Mathematics is the language of engineering (as well as science).

Yes
Yes, pursuing a major in mathematics can lead to a successful career in various fields such as finance, data analysis, engineering, and research. Mathematics provides strong analytical and problem-solving skills that are highly valued in many industries.
