Answer: 9 / 20
Step-by-step explanation:
Convert both of the fractions to decimals and then sum them up.
= 2/10 = 0.2

= 0.2 + 0.25
= 0.45
The convert this figure back to fractions.
As it is 2 digits after the decimal, it is over 100 when converted.
= 45 / 100
Take it to the lowest term:
= 45 / 100 ÷ 5
= 9 / 20

Step-by-step explanation:
Given that :
Summit of Mount Washington = 6288 ft
Location of Carter notch = elevation of 3288 ft
The change in elevation will be :
A reduction in elevation from the summit of Mount Washington to Carter Notch
(6288ft - 3288ft) = 3000ft
Since it is a reduction from the initial elevation point or height, Then the change in elevation will be negative ;
= - 3000ft
