GLOBAL VIOLYMPIC đó!
Dịch: Bella mất 3 giờ để lau dọn nhà. Anna mất 2 giờ để lau dọn nhà. Hỏi hai bạn cùng lau dọn nhà thì mất bao lâu
Giải:
Trung bình 1 giờ Bella lau được là:
\(1:3=\frac{1}{3}\) (ngôi nhà)
Trung bình 1 giờ Anna lau dọn được là:
\(1:5=\frac{1}{5}\) (ngôi nhà)
Vậy nếu 2 bạn cùng nhau dọn thì trung bình dọn được là:
\(\frac{1}{2}+\frac{1}{3}=\frac{5}{6}\) (ngôi nhà)
=> Cả 2 bạn cùng dọn thì xong ngôi nhà sau:
\(1:\frac{5}{6}=\frac{6}{5}\) (giờ)
Đáp số: \(\frac{6}{5}\)giờ
