Question

Learn with an example Tina is making a banner for her little sister's birthday party. She tapes together pieces of construction paper until the banner is 3 feet long. Each piece of paper is 9 inches long. How many pieces of paper does Tina need? pieces of paper Submit

Answer 1

The total length of the banner is B=3 feet.

The pieces of paper are of P=9 inches long per piece.

Then we can calculate the amount of pieces of paper dividing B by P as:

`(B)/(P)=\frac{3\text{ ft}}{9\frac{\text{ in}}{\text{ piece}}}\cdot\frac{12\text{ in}}{1\text{ ft}}=4\text{ pieces}`

The banner, in inches, is equal to 3*12 = 36 inches long. Divided by 9 inches per paper, 36/9 = 4 pieces are needed.

Answer: 4 pieces of paper.
