<span>To find what percent one number is of another number, write the two numbers as a fraction, with the whole as the denominator. Then find an equivalent ratio with a denominator of 100 and write that ratio as a percent.</span>
You have to have the same unit of measure. Here your units are "minutes" and "seconds". In order to compare the two, you must change to 240 seconds into minutes (dividing by 60 = 4 mins) OR change the 5 minutes into seconds (multiply by 60 to give you 300 seconds)

Answer:
Step-by-step explanation:
(4b^2+3)(4b^2-3)
since it is the expanded form of formula a^2-b^2=(a+b)(a-b) we can write,
=(4b^2)^2-(3)^3
=16b^4-9
