First we have to find out the LCM of 4 and 5 The LCM is 20 So 1/4 × 5 , 1/5 × 4 = 5/20 , 4/20 5/20 ×10 , 4/20 ×10 = 50/200 , 40/200 So three rational numbers could be 42/200 = 21/100 , 49/200 and 43/200

As per BODMAS rule, we need to do the bracket work first. So, [8 - 4/2 ÷ 2 - 2] × 1/2. [4/2 ÷ 0] × 1/2. [2 ÷ 0] × 1/2. 0 × 1/2 = 0.

Anandika Chakraborty 4 years, 2 months ago

So, As per your question follow the below steps :- Given, X + Y = 180° 3X + 20 Let, the common factor be X. So, X + Y = 180° (3X + 20) + X = 180° 3X + X = 180° - 20° 4X = 60° X = (60 ÷ 4)° So, X = 15° If X is 15° then, 3X + 20 = 3 × 15 + 20 = 45 + 20 = 65° And x = 15°
