Kieran's savings is 9/2 of Simons savings, So
a) Kieran has 9 parts and Simon has 2 parts,
when together they have 11 parts,
9+ 2 = 11
So the ratio of Kieran's parts to the total saving
= 9parts : 11parts
= 9 : 11
b) Times when the total amount of money saved is Kieran's savings
Kieran/total = 9parts/11parts = 9/11
So, kieran's saving is 9 times.
c) times the total amount of money saved is Simon's savings
Simon/total = 2/11
So. Simon's saving is 2 times the total saving.
d) Simon saves$28 less than Kieran
9x -2x = 28
7x = 28
x = 4
so Kieran saved 9x = $36
Simon saved 2x = $8
and if we look simon saves $28 less than kieran
$36 - $8 = $28
So together they saved $36+$8 = $44
