PLEASE MARK ME AS BRAINLIEST ^_^
Step-by-step explanation:
s= smallest share, l= largest share
\frac{s}{2}
2
s
=\frac{s+540}{7}
7
s+540
multiply by LCM 14 (by both sides of the equation)
so now the equation is
7s = 2(s+540)
7s = 2s + 1080
subtract 2s from both sides of the equation
so now we have:
5s = 1080
now we can divide the 5 from both sides
s = 216, which is the smallest share!
largest share ca be calculated by adding 540 to the smallest share
216+540 = 756
and from here, N equals £1296!
