C1 : \(\frac{7}{11}\):\(\frac{3}{5}\)+\(\frac{4}{11}\):\(\frac{3}{5}\)
=\(\frac{7}{11}\)x\(\frac{5}{3}\)+\(\frac{4}{11}\)x\(\frac{5}{3}\)
=\(\frac{35}{33}\)+\(\frac{20}{33}\)
=\(\frac{55}{33}\)=\(\frac{5}{3}\)
C2: \(\frac{7}{11}\):\(\frac{3}{5}\)+\(\frac{4}{11}\):\(\frac{3}{5}\)
= \(\frac{3}{5}\)x (\(\frac{7}{11}\)+\(\frac{4}{11}\))
=\(\frac{3}{5}\)x 1= \(\frac{3}{5}\)
\(C1:\frac{7}{11}:\frac{3}{5}+\frac{4}{11}:\frac{3}{5}\)
\(=\frac{7}{11}x\frac{5}{3}+\frac{4}{11}x\frac{5}{3}\)
\(=\frac{35}{33}+\frac{20}{33}\)
\(=\frac{55}{33}=\frac{5}{3}\)
\(C2:\frac{7}{11}:\frac{3}{5}+\frac{4}{11}:\frac{3}{5}\)
\(=\frac{7}{11}x\frac{5}{3}+\frac{4}{11}x\frac{5}{3}\)
\(=\frac{5}{3}x\left(\frac{7}{11}+\frac{4}{11}\right)\)
\(=\frac{5}{3}x1=\frac{5}{3}\)
a, cách 1 : 7/11 : 3/5 + 4/11 : 3/5 b, cách 1 : [ 6,24 + 1,26 ] : 0,75
=[ 7/11 + 4/11 ] : 3/5 = 7,5 : 0,75
= 1 : 3/5 = 10
= 5/3 cách 2 : [ 6,24 + 1,26 ] : 0,75
cách 2 :7/11 : 3/5 + 4/11 : 3/5 = 6,24 : 0,75 + 1,26 : 0,75
=35/33 + 20/33 = 8,32 + 1,68
=55/33 = 10

\(\frac{7}{11}:\frac{3}{5}+\frac{4}{11}:\frac{3}{5}\)
= ( \(\frac{7}{11}+\frac{4}{11}\)) : \(\frac{3}{5}\)
= 1 : \(\frac{3}{5}\)
= \(\frac{5}{3}\)
Cách 1: 7/11:3/5+4/11:3/5

C1 : \(\frac{7}{11}:\frac{3}{5}+\frac{4}{11}:\frac{3}{5}=\frac{35}{33}+\frac{20}{33}=\frac{55}{33}=\frac{5}{3}\)

a) C1:
7/11 : 3/5 + 4/11 : 3/5 = 7/11 x 5/3 + 4/11 x 5/3
= (7/11 + 4/11) x 5/3
= 1 x 5/3
= 5/3
C2:
7/11 : 3/5 + 4/11 : 3/5 = (7/11 + 4/11) : 3/5
= 1 : 3/5
= 1 x 5/3
= 5/3
b) C1:
(6,24 + 1,26) : 0,75 = 7,5 : 0,75
= 10
C2:
(6,24 + 1,26) : 0,75 = 6,24 : 0,75 + 1,26 : 0,75
= 8,32 + 1,68
= 10
\(\frac{7}{11}:\frac{3}{5}+\frac{4}{11}:\frac{3}{5}\)
C1 : \(=\frac{7}{11}.\frac{5}{3}+\frac{4}{11}.\frac{5}{3}\) C2 : \(=\left(\frac{7}{11}+\frac{4}{11}\right):\frac{3}{5}\)

Cách 1:
7 11 : 3 5 + 4 11 : 3 5 = 7 11 + 4 11 : 3 5 = 11 11 : 3 5 = 1 : 3 5 = 5 3
Cách 2:
7 11 : 3 5 + 4 11 : 3 5 = 35 33 + 20 33 = 55 33 = 5 3
