✽ Question ✽
Exprees the following using integers :-
a. 15°C above zero
b. 20°C below zero
c. A profit of ₹ 500
d. A loss of ₹ 700
e. The height of a hill is 5000 m
f. The depth of a well is 50 m
✽ To find ✽
Express them using integer.
✽ Solution ✽
a. 15°C above zero
Since, the temperature is above 0℃, it can be expressed as positive integer.
So,
15℃ above zero = 15℃
b. 20°C below zero
Since, the temperature is below 0℃, it can be expressed as negative integer.
So,
20℃ below zero = -20℃
c. A profit of ₹ 500
Since, ₹ 500 is the profit and so is greater than 0, it can be expressed as positive integer.
So,
a profit of ₹ 500 = ₹ 500
d. A loss of ₹ 700
Since, ₹ 500 is the loss and so is less than 0, it can be expressed as negative integer.
So,
a loss of ₹ 700 = ₹ -700
e. The height of a hill is 5000 m
Since, 5000 m is the height of a hill, it is above sea level and can be expressed as positive integers.
So,
the height of a hill is 5000 m = 5000 m
f. The depth of a well is 50 m
Since, 5000 m is the depth of a well, it is below sea level and can be expressed as negative integers.
So,
the depth of a well is 50 m = -50 m
✽ Therefore ✽
The answer of:
a. is 15℃
b. is -20℃
c. is ₹ 500
d. is ₹ -700
e. is 5000 m
f. is -50 m
You can also put a '+' sign before positive integers.
Hope this helps you.
