quy đồng mẫu số : 3/8 = 9/24 1/6=4/24
15/24 -9/24-4/24=2/24
\(\frac{15}{24}\)- \(\frac{3}{8}\)-\(\frac{1}{6}\)=\(\frac{15}{24}\)-\(\frac{9}{24}\)-\(\frac{4}{24}\)
= \(\frac{15-9-4}{24}\)= \(\frac{2}{24}\)=\(\frac{1}{12}\)
Trả lời:
\(\frac{15}{24}\)- \(\frac{3}{8}\)- \(\frac{1}{6}\)= \(\frac{15}{24}\)- \(\frac{9}{24}\)- \(\frac{4}{24}\)= \(\frac{6}{24}\)- \(\frac{4}{24}\)= \(\frac{2}{24}\)= \(\frac{1}{12}\)
Đáp án là \(\frac{1}{12}\)
Chúc bn học tốt
