Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri
Ne4ueva [31]

Answer:

7\frac{1}{2} pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

x:1=5:\frac{2}{3}

We can rewrite the ratios as a fraction.

\frac{x}{1}=\frac{5}{\frac{2}{3}}

This simplifies to

x=\frac{15}{2}

Or

x=7\frac{1}{2}

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: 5:40

Let y corresponds to 60 seconds (1 minutes).

Then:

y:60=5:40

We rewrite as fraction:

\frac{y}{60}=\frac{5}{40}

Multiply both sides by:

y=\frac{5}{40}\times 60

y=\frac{300}{40}

y=\frac{15}{2}

y=7\frac{1}{2}
