Integers

So, in this question we are using integers rules.

What are Integers?

>> Integers are the numbers that can be positive, negative, or zero, numbers with no fractional part (no decimals).

The examples of integers are, 1, -2, 7, -8, 9,-13, 24 etc.

Integers Rules :

1. (+) (+) = +

2. (-) (-) = +

3. (+) (-) = -

So, by keeping these rules in mind we will solve the following question.

Step-by-step explanation:

Solution :

1. (a) Temperatures : -

Lahulspiti : -8°C

Srinagar : -2°C

Shimla : 5°C

Ooty : 14°C

Bengluru : 22°C

(b)

To Find :

Difference between the hottest and the coldest place.

Answer :

Hottest Place = Bengluru

Temp. of Bengluru = 22°C

Coldest Place = Lahulspiti

Temp. of Lahulspiti = -8°C

Difference = Hottest place - Coldest place

= 22 - (-8)

= 22 + 8

= 30°C

=> Difference between the 2 places is 30°C.

(c)

To Find :

Difference between temperatures of Lahulspiti and Srinagar .

Answer :

Lahulspiti = -8°C

Srinagar = -2°C

Difference = (-8) - (-2)

= -8 +2

= -6°C

=> Difference between temp. of 2 places

is -6°C.

(d)

To Find :

Ist Situation :

Can we say that temperatures of Srinagar and Shimla taken together is less than that of Shimla?

II nd Situation :

Is the taken together temperature also less than the temperature of Srinagar?

Answer :

Ist Case :

Srinagar = -2°C

Shimla = 5°C

Sum = Srinagar + Shimla

= -2 + 5

= 3°C

: Sum of Srinagar and Shimla is 3°C.

Temperature of Shimla = 5°C

Taken Together Temp. < Shimla

3°C. < 5°C

Hence, we can say that temp. taken together of Shimla and Srinagar taken together is less than the temp. of Shimla.

IInd Case :

To Find:

Is it also less than the temp. at Srinagar?

Temp. of Srinagar = -2°C

Taken together temp. sum = 3°C

-2 < 3

Hence, no the temp. of Shimla and Srinagar taken together is not less than the temperature of Srinagar..

-2°C < 3°C
