## DAV Class 5 Maths Ch 15 Worksheet 2 Solutions

Question 1.

Convert the following temperature in the Fahrenheit Scale.

(a) 20°C

Solution:

20°C

Step 1: Multiply 20 by \(\frac{9}{5}\)

20 × \(\frac{9}{5}\) = 36

Step 2: Add 32 to 36

32 + 36 = 68

So, 20°C = 68°F

(b) 45°C

Solution:

45°C

Step 1: Multiply 45 by \(\frac{9}{5}\)

45 × \(\frac{9}{5}\) = 81

Step 2: Add 32 to 81

32 + 81 = 113

So, 45°C = 113°F

(c) 75°C

Solution:

75°C

Step 1: Multiply 75 by \(\frac{9}{5}\)

75 × \(\frac{9}{5}\) = 135

Step 2: Add 32 to 135

32 + 135 = 167

So, 75°C = 167°F

(d) 100°C

Solution:

100°C

Step 1: Multiply 100 by \(\frac{9}{5}\)

100 × \(\frac{9}{5}\) = 180

Step 2: Add 32 to 180

32 + 180 = 212

So, 100°C = 212°F

(e) 85°C

Solution:

85°C

Step 1: Multiply 85 by \(\frac{9}{5}\)

85 × \(\frac{9}{5}\) = 153

Step 2: Add 32 to 153

32 + 153 = 185

So, 85°C = 185°F

(f) 10°C

Solution:

10°C

Step 1: Multiply 10 by \(\frac{9}{5}\)

10 × \(\frac{9}{5}\) = 18

Step 2: Add 32 to 18

32 + 18 = 50

So, 10°C = 50°F
