Last week Martha read two fifths of an adventure book and this week she has read
shutvik [7]

Answer: Check explanation.

Step-by-step explanation: If she has 140 pages left to read, and completed 2/5 of the book last week, and 1/4 of the book this week, then we have to divide the pages left to read (140) by the fraction of pages she read last week (2/5), and this week (1/4).

When you divide 140 by 2/5 by 1/4, you get 1400. Hope this helped!
