Ahh, fractions and word problems, the bane of my education (seriously, why do we bother with fractions when decimals are easier to compute and express?)

The higher the level of the course I was taking, the less test markers cared about the actual final answer. If you used the correct equations, simplifying the final answer to a faction rather than a decimal or leaving constants like pi and e in there was good enough for full marks.
Generally more accurate, too, because you're not rounding the number but leaving it as the true value because 1/3 != 0.333333. It's better to do it this way if there's multiple steps, too, since you can gather or cancel out like terms if you leave them as variables instead of converting and rounding to some decimal.
People have already commented on fractions, there's a lot of math that is way easier to keep accurate by leaving in fractional form as it goes.
For word problems, done correctly, the math is pointless if you can't map it to more realistic scenarios. In terms of applying math to the real world, it's supremely rare that the world just spits out the equation ready for you to solve, the ability to distill a scenario described by prose to a mathemetical solution is critical. Problem is when they are handled incorrectly and have ambiguous solutions or parameters, but dealing with kids' homework, this is pretty rare, though it's admittedly utterly infuriating when it comes up.

I had situations like this at least a few times a year in school.
I usually managed to convince the teacher I was right.
And yah this kid is almost certainly ND.
Not just the answer, but the handwriting screams dysgraphia.
It looks a lot like mine.

Is there any reason at face value why the teacher’s answer is correct? From my perspective the teacher is an idiot and missing some basic math skills.
Marty ate 66% vs the other kid’s 83%, no way “marty ate more” with the information given.
no way “marty ate more” with the information given.
that is the 'Expected' answer
So this is sort of a true/false math problem given to us, the viewer, out of context.

Marty ate some of someone else's pizza
Reminds me of the stack of frozen mini pizzas you could get in the 80s.
