Ta có: \(\frac{2}{3}\)tấm vải xanh = \(\frac{3}{5}\)tấm vải đỏ => \(\frac{6}{9}\)tấm vải xanh = \(\frac{6}{10}\)tấm vải đỏ (1)
\(\frac{2}{3}\)tấm vải xanh = \(\frac{6}{7}\)tấm vải trắng => \(\frac{6}{9}\)tấm vải xanh = \(\frac{6}{7}\)tấm vải trắng (2)
Từ (1) và (2) => \(\frac{6}{9}\)tấm vải xanh = \(\frac{6}{10}\)tấm vải xanh = \(\frac{6}{7}\)tấm vải trắng
Coi số m của tấm vải xanh là 9 phần, tấm vải đỏ là 10 phần và tấm vải trắng là 7 phần
Tổng số phần bằng nhau:
9+10+7=26 phần
Số m tấm vải xanh dài là:
182:26x9=63 m
Số m tấm vải đỏ dài là:
182:26x10=70 m
Số m tấm vải trắng dài là:
182-63-70=49 m
Đáp/Số: tấm vải xanh dài 63 m
tấm vải đỏ dài 70 m
tấm vải trắng dài 49 m
