Step-by-step explanation:
t= how far his scooter can travel on 2.5 gallons of gas
Start by setting up a ratio
53:1= t:2.5
Rewrite as fractions
= 
Cross multiply
1(t)= 53(2.5)
Simplify
t= 132.5
Walter's scooter can travel 132.5 miles on 2.5 gallons of gas

ANSWER
Find out the how old was we when he died.
To proof
Let us assume that the age of the Adam be x
As given
Adam lived a quarter of his life as a boy as fifth as a young man, a third in middle-age and 13 years in retirement.
L.C.M of denominator i.e ( 4,5,3) =60
than the equation becomes
60x = 15x + 12x +20x +780
60x - 47x = 780
13x = 780
x = 60 years
therefore the Adam age when he died is 60 years.
Hence proved

Step-by-step explanation:
Stratified sampling technique is one in which the groups of data are divided into smaller groups or strata, based on shared common characteristics in these groups, and the samples randomly selected from each group in a proportional way. In this example, the sub-groups used is "times of the day" ie. morning, afternoon or evening. Other strata that can be used are; age, gender, continents etc. Stratification is done when the researcher wants to understand the relationships between the two or more groups. Stratified random sampling is also known as proportional random sampling or quota random sampling.
