Jenny is remodeling her bathroom floor. She is going to use tile that is 3/4 foot long. If her bathroom is 7 1/3 feet long, how many tiles will she need to first cover the length of the bathroom?
7.3333 / 0,75 = 9.7777 tiles
She needs 9 whole tiles and most of the tenth tile.
Thanks, Ms. Sue
You're welcome, Kia.
To find out how many tiles Jenny will need to cover the length of her bathroom floor, we need to divide the total length of the bathroom by the length of each tile.
Jenny's bathroom is 7 1/3 feet long. We can convert this mixed number into an improper fraction by multiplying the whole number (7) by the denominator (3), then adding the numerator (1). This gives us a total of 22/3 feet.
Now, we can divide this length by the length of each tile - 3/4 foot.
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. Let's set up the equation:
(22/3 feet) ÷ (3/4 foot)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(22/3 feet) × (4/3 foot)
Now, let's simplify the fractions:
- Multiply the numerators: 22 × 4 = 88
- Multiply the denominators: 3 × 3 = 9
So, (22/3 feet) ÷ (3/4 foot) is equal to (88/9 feet).
Since each tile is 3/4 foot long, we need to divide the length of the bathroom by the length of each tile:
(88/9 feet) ÷ (3/4 foot)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(88/9 feet) × (4/3 foot)
Now, let's simplify the fractions:
- Multiply the numerators: 88 × 4 = 352
- Multiply the denominators: 9 × 3 = 27
So, (88/9 feet) ÷ (3/4 foot) is equal to (352/27 feet).
Therefore, Jenny will need approximately 13 tiles (rounded to the nearest whole number) to cover the length of her bathroom floor.
