\(\text{Ta có: 10/7 x 2/3 + 6/5 : 3/10 - 2/3 x 3/7 = 10/7 x 2/3 + 4 - 2/3 x 3/7
}\)
\(\text{ = 2/3 x ( 10/7 - 3/7) + 4
}\)
\(\text{= 2/3 x 1 + 4}\)
\(\text{ = 2/3 + 12/3
}\)
\(\text{ = 14/3}\)
Ta có:
10/7 x 2/3 + 6/5 : 3/10 - 2/3 x 3/7
= (10/7 - 3/7) x 2/3 + 6/5 : 3/10
= 1 x 2/3 + 4
= 2/3 + 4
= \(4\frac{2}{3}\)
Đáp số: \(4\frac{2}{3}\)
Ta có
10/7 x 2/3 + 6/5 : 3/10 - 2/3 x 3/7
= 2/3 x [ 10/7 - 3/7 ] + 4
= 2/3 x 1 + 4
= 2/3 + 12/3
= 14/3
Vậy : 10/7 x 2/3 + 6/5 : 3/10 - 2/3 x 3/7 = 14/3
