total of ages now is 67 + 4 + 4 = 75
S=shelly
M= Michelle
Michelle is 3 yrs younger than Shelly so use S-3
S +M = 75
replace M with S-3 to get:
S +S-3=75
2S=78
s=39
So shelly is 39
Michelle is 3 years younger = 39-3 = 36
35% off means that now it costs 100%-35%=65% of the original price
<span>£78 ---- 65%
x------100%
x=78*100/65=120</span>£<span>
or
part/whole=0.65
78/whole=0.65
whole =78/0.65 =120 </span>£
Answer:
yes because it is the opposite side
in 3.4653, there is one digit to the left of the decimal point, that is the ones position
in 34.653, there are 2 numbers to the left of the decimal point, the 3 is located in the tens place
so 34.653 is greater than 3.4653
