Put a 1 under the 4 to make 4/1. it will still be 4. then multiply straight across 9 x 4=36 and 1 x 5=5 so the answer is 36/5.
hope this helped:)

First of all you need to change it into a mixed number
wich would equal 5 4/5 witch equals 5.8 then you would multiple

4 x 5.8 and that would equal 23.2

Answer:

$229$ Square foot need to be painted, if width is equal to $10$ feet

Step-by-step explanation:

Complete question -

Maya wants to paint one wall in her room blue. The wall is 22,9 feet high, and have no doors or windows. How many square feet need to be painted?

Solution -

The square feet need to be painted will be equal to the product of height and width of the wall i.e surface area of the wall

Let the width of the wall be $10$ feet

Surface area of the wall $= H * W$

Where H is the height of the wall in feet

W is the width of the wall in feet

Substituting the given values in above equation, we get -

$22.9 * 10\\$

$229$ Square foot.

Thus, $229$ Square foot need to be painted
