a) 1/2
b) 18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9
Nhớ k cho mk nha
a)1/2
b)Vì 18/17 <17/16 <16/15<15/14< 14/13< 13/12< 10/9
Nên, ta có:
18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9.
\(\dfrac{9}{54}=\dfrac{1}{6}=\dfrac{4}{24}< \dfrac{7}{24}\)
\(\dfrac{7}{24}< \dfrac{12}{24}< \dfrac{16}{24}=\dfrac{2}{3}\)
\(\dfrac{2}{3}< \dfrac{2+1}{3+1}=\dfrac{3}{4}\)
\(\dfrac{3}{4}< \dfrac{3+2}{4+2}=\dfrac{5}{6}\)
\(\dfrac{5}{6}< \dfrac{5+2}{6+2}=\dfrac{7}{8}\)
\(\dfrac{7}{8}< \dfrac{7+9}{8+9}=\dfrac{16}{17}\)
Vậy \(\dfrac{9}{54}< \dfrac{7}{24}< \dfrac{2}{3}< \dfrac{3}{4}< \dfrac{5}{6}< \dfrac{7}{8}< \dfrac{16}{17}\)
a , Theo thứ tự từ bé đến lớn : 1/12 , 2/3 , 3/4 , 5/6
b, Tính
a, 3/ 4 + 2/3 + 5/12 = 9/12 + 8/12 + 5/12 = 11/6
b, 7/8 - 7/16 - 11/32 = 28/32 - 14/32 - 11/32 = 3/32
c, 3/5 x 2/7 x 5/6 = 3 x 2 x 5 / 5 x 7 x 6 = 3 x 2 x 5 / 5 x 7 x 3 x 2 = 1/7
d , 15/16 : 3/8 x 3/4 = 15/16 x 8/3 x 3/4 = 15 x 8 x 3 / 16 x 3 x4 = 3 x 5 x 8 x 3 / 8 x 2 x 3 x 4 = 15/8
a) 1/12; 2/3; 3/4; 5/6
b)
a) 3/4 + 2/3 + 5/12 = 9/12 + 8/12 + 5/12 = 17/12 + 5/12 = 22/12 = 11/6
b) 7/8 - 7/16 - 11/32 = 28/32 - 14/32 - 11/32 = 14/32 - 11/32 = 3/32
c) 3/5 x 2/7 x 5/6 = 6/35 x 5/6 = 30/210 = 1/70
d) 15/16 : 3/8 x 3/4 = 15/16 x 8/3 x3/4 = 120/48 x 3/4 = 360/192 = 8/15
