sarah has 150 pages to read for her homework. if she has already read 60% of the pages, how many pages does she have left to read?

To find out how many pages Sarah has left to read, we start by calculating how many pages she has already read.

1. **Calculate the number of pages Sarah has read:**

   Sarah has read 60% of the total 150 pages. We can find this by multiplying 150 by 60%.

\[
\text{Pages read} = 150 \times 0.60 = 90 \text{ pages}
\]

2. **Determine the number of pages left:**

   Subtract the number of pages she has read from the total:

\[
\text{Pages left} = 150 - 90 = 60 \text{ pages}
\]

So, Sarah has **60 pages** left to read.
