Answer 1

Five out of every nine pencils are yellow. You can make a fraction for this:

$\frac{5}{9}$

You have 45 pencils. To find the amount of yellow pencils, multiply the fraction by 45. First set up the equation:

$\frac{5}{9} \times 45$

Make 45 as a fraction so that you'll be multiplying fractions together. It will also make it easier.

To write a whole number as a fraction, ALWAYS make the whole number the denominator and 1 as the numerator.

$45 \rightarrow \frac{45}{1}$

Here is the "new equation":

$\frac{5}{9} \times \frac{45}{1}$

Multiply. You multiply the numerators and denominators together.

$\frac{5}{9} \times \frac{45}{1} =\frac{225}{9} = 25$

That means 25 pencils are yellow

Answer 2

5/9 * 45/1 is 25

25 pencils are yellow hope this is helpful, have a good day! :D
