Serena had 7 4/9 yd of tape.
She used 2 1/9 yd.
How much tape does she have left?

        7 4/9
     -  2 1/9
--------------

Since both fractions have the same denominator, and since the lower fraction is smaller than the upper fraction, you can subtract the fractions by subtracting the numerators and using the same denominator. Then also subtract the whole numbers.

        7 4/9
     -  2 1/9
--------------
        5 3/9

The difference is 5 3/9.
3/9 can be reduced since both 3 and 9 are divisible by 3, so we divide both 3 and 9 by 3 to get 1/3.

Answer: 5 1/3 yards

NISA [10]
First, let's write down this inequality:
<span>There are at least 245 students enrolled in the school.

 y≥245

This inequality says what the sentence says!

now, the number of teachers must be:
x≥2*(y/25)
 (two times the number of groups of students of 25!)

so those two inequalities, taken together will be the answer!
