Step by step
The question
Question: type 7/9 as an SAT answer.
79
1 Count the characters
The answer box takes 5 characters.
7/9 has 3.
It fits.
7/9: 3 characters, up to 5 fit
2 Type it in
We type 7/9.
As a decimal: 7 ÷ 9 is 0.777777 and more.
7 ÷ 9 = 0.777777…
A decimal works too, if it fills the box.
Cut it after 4 digits: .7777.
Or round it: .7778.
Both are OK.
.7777 or .7778 also OK
Careful!
Not .78.
It uses only 2 digits, and the box has room for 4.
That is marked wrong.
Careful: not .78 ✗
Let's look back.
First: count the characters.
Last: type it in.
Answer
.7777 or .7778 also OK
