A = 10101 . ( 5 / 111111 + 5 / 222222 - 4 / 3 . 7 . 11 13 37 )
1,. Tính
A=10101*(5/111111+5/222222+4/3*7*11*13*37
2, Rut gon phan so
A. 6*9-2*17/63*3-119
B. 2*3+4*6+14*21/3*5+6*10+21*35

C=10101(5/111111+5/222222+4/111111)
`10101(5/111111+5/222222+4/111111)`
`=10101(10/222222+5/222222+8/222222)`
`=10101xx23/222222`
`=23/22`

(1/2-0,75).(0,2-2/5):9/5-13/12
2/3+2/7-1/14:-1-3/7+3/28
tính hợp lý nhất
10101.(5/111111+5/222222-4/3.7.11.13.37)
10101.(5/111111+5/222222-4/3.7.11.13.37)
H=(9 30303/80808+7 303030/484848)+4.03
I=10101.(5/111111+5/222222-4/3.7.11.13.37)
giải thích đầy đủ ạ
C=10101.(5/111111 + 5/222222 + 4/3.7.11.13.37 ) = ?
\(C=10101.\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{3.7.11.13.37}\right)\)
\(C=10101.\frac{23}{222222}\)
\(C=\frac{23}{22}.\)
C=10101.(5/111111 + 5/222222 + 4/3.7.11.13.37 )
