Descrption
<p style = "box - sizing: border - box; margin: 0px 0px 8px; padding: 0px; min - height: 24px; font - size: 18px; line - height: 24px; font - family: ProximaNova, Helvetica, Arial, sans - serif; background - color: #ffffff;">First, we need to find out 40% of the 50 girls. That is 50 x 0.4 = 20 girls.</p> <p style = "box - sizing: border - box; margin: 0px 0px 8px; padding: 0px; min - height: 24px; font - size: 18px; line - height: 24px; font - family: ProximaNova, Helvetica, Arial, sans - serif; background - color: #ffffff;">Next, we need to find out 50% of the 70 boys. That is 70 x 0.5 = 35 boys.</p> <p style = "box - sizing: border - box; margin: 0px 0px 8px; padding: 0px; min - height: 24px; font - size: 18px; line - height: 24px; font - family: ProximaNova, Helvetica, Arial, sans - serif; background - color: #ffffff;">Therefore, 20 + 35 = 55 people attended.</p> <p style = "box - sizing: border - box; margin: 0px 0px 8px; padding: 0px; min - height: 24px; font - size: 18px; line - height: 24px; font - family: ProximaNova, Helvetica, Arial, sans - serif; background - color: #ffffff;">In total there were 50 + 70 = 120 people.</p> <p style = "box - sizing: border - box; margin: 0px 0px 8px; padding: 0px; min - height: 24px; font - size: 18px; line - height: 24px; font - family: ProximaNova, Helvetica, Arial, sans - serif; background - color: #ffffff;">So the percent would be 55/120 = 11/24 ≈ 45.83% ≈ 46%.</p>
