tim phan so co tu so bang 3, lon hon 1 phan 6 nhung be hon 1 phan 5
3/17 3/16 đúng ủng hộ mình nha
tim cac phan so co tu so la 3 ma lon hon 1/6 nhung nho hon 1/5 ?
\(\frac{1}{6}< \frac{3}{a}< \frac{1}{5}\)
\(\frac{3}{18}< \frac{3}{a}< \frac{3}{15}\)
\(\frac{3}{a}=\frac{3}{17}=\frac{3}{16}\)
Gọi phân số đó là a, ta có:
1/5> a > 1/6 hay, quy đồng mẫu ta đc:
6x/30k >a >5y/30k ,, vậy vô hạn phân số
Ta có:
\(\frac{1}{6}=\frac{1\cdot3}{6\cdot3}=\frac{3}{18}\)
\(\frac{1}{5}=\frac{1\cdot3}{5\cdot3}=\frac{3}{15}\)
Mà \(\frac{3}{18}< \frac{3}{x}< \frac{3}{15}\left(xEN\right)\)
=>\(xE\left\{17;16\right\}\)
Vậy.......
