Question:
If +7°C represent 7°C above freezing point, then what will 15°C below freezing point ?
Answer:
-15°C is the correct answer.
Step-by-step explanation:
This question is based on integers.
Statement - 1: +7°C represent 7°C above freezing point.
Statement - 2: -15°C represent 15°C below freezing point.
In statement - 1 it is +7°C because it says above means positive.
In statement - 2 it is -15°C because it says below means negative.
Integers are those whole numbers which which have positive sign or negative sign including having no sign.
Example=> Increase(+) and Decrease(-) of value of product
Product value gets increased by Rs. +15
Product value gets decreased by Rs. -15
Given : 7°C represent 7°C above freezing point,
To find : what will be 15°C below freezing
Solution:
7°C represent 7°C above freezing point
=> Freezing point is 7 - 7 = 0°C
Now 7°C represent 7°C above freezing point
=> point above Freezing point are + ve
Hence point below the freezing point will be - ve
as it can be seen as Number line on Y - axis where point above zero are + Ve and below zero are - ve
Here Freezing point is Zero
Hence 15°C below freezing point means point below 0
hence it will be - 15°C
- 15°C will represent 15°C below freezing
