(70-63):(63-60)=7:3
Male: 100÷(7+3)×7=70.
Female student: 100-70=30.
Equation:
Solution: Suppose there are x boys and 100-x girls.
Equivalence relationship: total score of boys+total score of girls = total score of the whole school.
60x+70( 100-x)= 100×63
60x+7000-70x=6300
10x=700
x=70
100-70=30 people
A: There are 70 boys and 30 girls.
