In Yuxin primary school, 108 people participated in the school's science and technology group, of which the number of boys was 1.4 times that of girls?
Suppose there are x girls, & nbsp; & nbsp; X + 1.4x = 108, & nbsp; & nbsp; & nbsp; 2.4x = 108, 2.4x / 2.4 = 108 / 2.4, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 45, 45 × 1.4 = 63, a: there are 63 boys and 45 girls
