Gọi số giấy của lớp 7A,7Bvà 7C thu gom lần lượt là: x;y;z(kg)(x;y;z>0)(x;y;z<100kg)
Vì x;y;z tỉ lệ lần lượt với 45;50;55 nên:
\(\dfrac{x}{45}=\dfrac{y}{50}=\dfrac{z}{55}\)
Vì tổng số giấy lớp 7A và 7C thu được nhiều hơn số giấy của lớp 7B là 100 kg nên:
(x+z)-y=100
Áp dung tính chất dãy tỉ số bằng nhau ta có:
\(\dfrac{x}{45}=\dfrac{y}{50}=\dfrac{z}{55}=\dfrac{\left(x+z\right)-y}{\left(45+55\right)-50}=\dfrac{100}{50}=\dfrac{1}{2}\)
Do đó: \(\dfrac{x}{45}\)=\(\dfrac{1}{2}\)\(\Rightarrow\)x=45.\(\dfrac{1}{2}\)=22,5
\(\dfrac{y}{50}=\)\(\dfrac{1}{2}\)\(\Rightarrow\)y=50.\(\dfrac{1}{2}\)=25
\(\dfrac{z}{55}\)=\(\dfrac{1}{2}\)\(\Rightarrow\)z=55.\(\dfrac{1}{2}\)=27,5
