số cần tìm là :
73/ 98 - 1/6 = 85/147

Nhớ K mik nha

8888 x 85 + 8888 x 10 + 8888 x 6 – 8888
= 8888 x ( 85 + 10 + 6 - 1 )
= 8888 x 100
= 888800

\(\dfrac{3\times4\times2\times14}{7\times4\times6}=\dfrac{3\times4\times2\times2\times7}{7\times4\times6}=\dfrac{6\times4\times2\times7}{7\times4\times6}=2\\ \dfrac{21\times18\times3\times4}{2\times6\times7\times9}=\dfrac{3\times7\times9\times2\times3\times2\times2}{2\times6\times7\times9}=\dfrac{3\times2}{1}=6\)
`177:x-96:x+21:x=6`
`(177-96+21):x=6`
`102:x=6`
`x=102:6`
`x=17`
Vậy `x=17`
177 : x - 96 : x + 21 : x = 6
= x : ( 177 - 96 + 21 ) = 6
= x : 102 = 6
= x = 6 x 102
= x = 612
