Answer 1

Answer:

a) 75% can also be written as 75/100 and on dividing the numerator and denominator of fraction 75/100 by 25 we get answer 3/4

b) 1) 12/30 × 100 = 40%

2) 40/250 × 100 = 16%

c) 1) 50/80 × 100 = 62.5%

2) 15/75 × 100 = 20%

3) 60/240 × 100 = 25%

Answer 2

We know that :-

Sin 60° = √3/2

Cos 30° = √3/2

Sin 30° = 1/2

cos 30° = 1/2

tan 45° = 1
