Step-by-step explanation:
Hope the photos help. The main thing to remember is to divide the number line in to equal parts ..all the places with temperatures below zero will be negative, so they will come to the left of the zero . All the places with temperatures above zero will come to the right of the zero .So mount abu and Amritsar will come to the right of the zero while Leh will come to the left of the zero.
Given : The temperature in Leh was 9°C below zero
in Amritsar it was 1°C above zero.
the temperature in Mount Abu was 12 °C .
To Find : Represent the temperatures of these places on number line.
Solution:
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
1 : Draw a line and mark some points at equal distance on it
Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on
The temperature in Leh was 9°C below zero
Go 9 step left to zero and Mark Leh
in Amritsar it was 1°C above zero.
Go 1 step right to zero and Mark Amritsar
in Mount Abu was 12 °C .
Go 12 step right to zero and Mark Mount Abu
