The label on the car's antifreeze container claims to protect the car between -40°C and 140°C. To covert Celsius temperature to
Fahrenheit temperature, the formula is
c= 5/9(F – 32). Write a compound inequality to determine the Fahrenheit temperature range at which the antifreeze protects the car.

Find out the what fraction of the sandcastle did they build together .
To prove
Let us assume that the fraction of the sandcastle they build together be x .
As given
Than the equation becomes
L.C .M of (3,7) = 21
solving
Therefore the fraction of the sandcastle did they build together be
Hence proved
