Answer:Of the 18 chairs, 6 are red
Step-by-step explanation:
Given total no of chairs =18
Ratio of red chairs to brown chairs =2:4=[tex]\frac{2}{4}[/tex]
So there are 6(2+4) parts chair out of which 2 are red and 4 are brown
∴ 6 part equals 18 chairs
1 part equals [tex]\frac{18}{6}[/tex]
=3 chairs
Now 2 part equals 2×3=6
i.e. there are 6 red chairs
