Bài 3:
Gọi số hs khá giỏi của lớp 7 lần lượt là a,b(a,b thuộc N*)
Theo đề bài ra , ta có:
\(\frac{a}{2}\)=\(\frac{b}{3}\)và a+b= 250
Áp dụng tính chất của dãy tỉ số bằng nhau ta có:
\(\frac{a}{2}\)=\(\frac{b}{3}\)=\(\frac{a+b}{2+3}\)=\(\frac{250}{5}\)=50
Khi đó: a = 50 x 2 = 100
b = 50 x 3 = 150
= 2
