Question

Paula started reading a book and read 1/12 of the book on the first day. The next day, she read 1/3 of the book. How much does she still need to read the book?

Answer 1

7/12

Step-by-step explanation

We have that Paula first read 1/12 of her book. Then she read, 1/3 of the book.

First, we have to find how much of the book she has read.

We do that by adding the amounts she has read.

That is:

`\begin{gathered} (1)/(12)+(1)/(3) \\ (1+(4\cdot1))/(12)=(1+4)/(12) \\ =(5)/(12) \end{gathered}`

Now, to find how much she still has to read, we have to subtract the fraction she has read from 1.

That is:

`\begin{gathered} 1-(5)/(12) \\ \Rightarrow\text{ }(12)/(12)-(5)/(12) \\ =(7)/(12) \end{gathered}`

Therefore, she still has to read 7/12 of the book.
