Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

Answer: ![\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D)
Step-by-step explanation:
![\frac{5}{7}-\left(-\frac{1}{7}\right)](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D-%5Cleft%28-%5Cfrac%7B1%7D%7B7%7D%5Cright%29)
Once you take off the parenthesis, your sign should change from negative to positive.
![\frac{5}{7}-\left(-\frac{1}{7}\right)=\frac{5}{7}+\frac{1}{7}\\\\\frac{5}{7}+\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D-%5Cleft%28-%5Cfrac%7B1%7D%7B7%7D%5Cright%29%3D%5Cfrac%7B5%7D%7B7%7D%2B%5Cfrac%7B1%7D%7B7%7D%5C%5C%5C%5C%5Cfrac%7B5%7D%7B7%7D%2B%5Cfrac%7B1%7D%7B7%7D)
The fractions now both have the same denominator. Thus, we can add the numerators.
![\frac{5+1}{7}\\\\5+1\\\\6=\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B1%7D%7B7%7D%5C%5C%5C%5C5%2B1%5C%5C%5C%5C6%3D%5Cfrac%7B6%7D%7B7%7D)
Therefore, ![\frac{5}{7}-\left(-\frac{1}{7}\right)=\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D-%5Cleft%28-%5Cfrac%7B1%7D%7B7%7D%5Cright%29%3D%5Cfrac%7B6%7D%7B7%7D)
