Gillian wrote a 10 page report on the florida everglades in 3 days. on the first day, she wrote 31/2 pages. on the second day she wrote 4 1/3 pages. how many pages did she write on the third day?

The number of pages Gillian wrote on the third day is pages

Step-by-step explanation:

Given

Number of days = 3 days

Pages of report = 10 pages

First day = 3½ pages

Second day = 4⅓ pages

Required

Number of pages written on the third day.

Let the number of pages written on the first, second and the third day be represented with F, S and T respectively.

So,

F = 3½ pages

S = 4⅓ pages

From the given data, we have that the report was 10 pages.

Hence,

F + S + T = 10 pages

F + S + T = 10

By substitution, we have

3½ + 4⅓ + T = 10

Convert mixed fractions to equivalent improper fraction.

Add fractions

Make T the subject of formula

Subtract

Recall that T represent number of pages written on the third day.

Hence, the number of pages Gillian wrote on the third day is pages
