7.
Discounted price X
————————— = ———
Original Price 100
45 x
—- = —-
72 100
Cross multiply
45 times 100= 4500
72 times x= 72x
72x=4500
Divide
4500/72= 62.5%

The leading coefficient is the number written in front of the variable with the highest exponent
The highest exponent is 5, hence the leading coefficient is the coefficient of x raised to power 5, this is equal to -1
The polynomial can be written as

Leading coefficient is ;
(3/10) / (4/5)
= (3/10) x (5/4)
= (3x5) / (10x4)
= 15/40
GCF = 5 so divide numerator and denominators by 5
= 3/8
The answer is 3/8
