QUESTION 1
Given that just over 3 quarters of Canadians live within a short distance of the USA border.
To write the fraction, 3 quarters as a decimal.
1 quarter = 1/4
3 quarters = 3 (1/4)
= 3/4
= 0.75
Therefore, just over 0.75 of Canadians live within a short distance of the USA border.
QUESTION 2
Given,
Amersham station is at 482 ft above sea level
Waterloo station is at 70 ft below sea level
Let the seal level be point 0
Position of Amersham station is at +482ft
Position of Waterloo station is at -70 ft
Height difference = +482 – (-70)
Since minus times minus equals plus
Height difference = 482 + 70
Height difference = 552ft
