Mona painted 1/5 of a wall white 2/12 grey and rest blue. what portion of tha wall was painted blue?

Answer»

HI there!

Answer :-

LET the portion be x.

⟹ \bf\red{ \frac{1}{5} + \frac{2}{12} + x = 1}

TAKE LCM and USE Transposition.

⟹ \bf\blue{x = \frac{60 - 12 - 10}{60} }

⟹ \bf\pink{x = \frac{38}{60} = \frac{19}{30} }
