DAV Class 5 Maths Ch 15 Worksheet 3 Solutions
Question 1.
Convert the following temperature in the Celsius Scale.
(a) 41°F
Solution:
41°F
Step 1: 41 – 32 = 9
Step 2: 9 × \(\frac{5}{9}\) = 5
So, 41°F = 5°C
(b) 113°F
Solution:
113°F
Step 1: 113 – 32 = 81
Step 2: 81 × \(\frac{5}{9}\) = 45
So, 113°F = 45°C
(c) 95°F
Solution:
95°F
Step 1: 95 – 32 = 63
Step 2: 63 × \(\frac{5}{9}\) = 35
So, 95°F = 35°C
(d) 212°F
Solution:
212°F
Step 1: 212 – 32 = 180
Step 2: 180 × \(\frac{5}{9}\) = 100
So, 212°F = 100°C
(e) 32°F
Solution:
32°F
Step 1: 32 – 32 = 0
Step 2: 0 × \(\frac{5}{9}\) = 0
So, 32°F = 0°C
(f) 122°F
Solution:
122°F
Step 1: 122 – 32 = 90
Step 2: 90 × \(\frac{5}{9}\) = 50
So, 122°F = 50°C
DAV Class 5 Maths Chapter 15 Worksheet 3 Notes
Converting Fahrenheit Scale into Celsius Scale
Example.
Convert 77°F into Celsius Scale.
Solution:
Step 1: Subtract 32 from 77
77 – 32 = 45
Step 2: Multiply 45 by \(\frac{5}{9}\)
45 × \(\frac{5}{9}\) = 25°C
So, 77°F = 25°C
