A dress maker had 27 yards of fabric.If she wanted to use the fabric to make 5 dresses,each using the same amount of fabric how

Alina [70]

Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6

Step-by-step explanation:

Given

Total fabric = 27 yards

Dresses to be made = 5

In order to find the measurement of fabric for one dress, the total fabric will be divided by number of dresses to be made.

So,

$Fabric\ for\ one\ dress = \frac{Total\ fabric}{No.\ of\ dresses}$

$Fabric\ for\ one\ dress = \frac{27}{5}\\=5.4\ yards$

The answer lies between the whole numbers 5 and 6

Hence,

Each dress will need 5.4 yards of fabric and the answer lies between 5 and 6
