M=9/40-11/60+13/84-15/112
M=9/40-11/60+13/84-15/112
tinh m
M=9/40-11/60+13/84-15/112
M=9/40-11/60+13/84-15/112=1/16
nhớ k cho mình nha
Thực hiện phép tính : M = \(\dfrac{9}{40}-\dfrac{11}{60}+\dfrac{13}{84}-\dfrac{15}{112}\)
Ta có: \(M=\dfrac{9}{40}-\dfrac{11}{60}+\dfrac{13}{84}-\dfrac{15}{112}\)
\(=\dfrac{378}{1680}-\dfrac{308}{1680}+\dfrac{260}{1680}-\dfrac{225}{1680}\)
\(=\dfrac{105}{1680}=\dfrac{1}{16}\)
9/40-11/60+13/84-15/112
tinh m=9/40-11/60+13/84-15/112
ai giai tui tich
Thực hiện phép tính sau:
M= 9/40- 11/60+ 13/84 - 15/112
Thực hiện phép tính : M = 9/40 - 11/60 + 13/84 - 15/112
M=9/40-11/60+13/84-15/112
M=27/120-22/120+52/336-45/336
M=1/24+1/48
M=2/48+1/48=3/48=1/16
Bài 5: Thực hiện phép tính: M=\(\dfrac{9}{40}\)-\(\dfrac{11}{60}\)+\(\dfrac{13}{84}\)-\(\dfrac{15}{112}\)
\(M=\dfrac{9}{40}-\dfrac{11}{60}+\dfrac{13}{84}-\dfrac{15}{112}\)
\(M=\left(\dfrac{90}{40}-\dfrac{11}{60}\right)+\left(\dfrac{13}{84}-\dfrac{15}{112}\right)\)
\(M=\dfrac{27}{120}-\dfrac{22}{120}+\dfrac{52}{336}-\dfrac{45}{336}\)
\(M=\dfrac{5}{120}+\dfrac{7}{336}\)
\(M=\dfrac{1}{24}+\dfrac{1}{48}\)
\(M=\dfrac{3}{48}=\dfrac{1}{16}\)
M=\(\dfrac{9}{40}-\dfrac{11}{60}+\dfrac{13}{84}-\dfrac{15}{112}\)
M=\(\dfrac{1}{24}+\dfrac{13}{84}-\dfrac{15}{112}\)
M=\(\dfrac{11}{56}-\dfrac{15}{112}\)
M=\(\dfrac{1}{16}\)
thực hiện phép tính
M= 9/40 - 11/60 + 13/84 - 15/112
kết quả là \(\frac{1}{16}\) tích mk nha
