Step by step
The question
Question: type −4/5 as an SAT answer.
−45
1 Count the characters
The answer box takes 6 characters.
−4/5 has 4.
It fits.
A negative answer gets one more character, for the minus sign.
−4/5: 4 characters, up to 6 fit
2 Type it in
We type −4/5.
4 ÷ 5 is −0.8.
It fits in the box too.
So −0.8 also works: it is the same number.
4 ÷ 5 = 0.8 also OK
Let's look back.
First: count the characters.
Last: type it in.
Answer
4 ÷ 5 = 0.8 also OK
