10/27: 1/27+7/27+2/27
13/12: 1/12+7/12+5/12
15/8:7/8+3/8+5/8
10/27 = 1/27+2/27+7/27
13/12 = 1/12+5/12+7/12
15/8 = 3/8+5/8+7/8
\(\dfrac{8}{3}=2\dfrac{2}{3}\)
\(\dfrac{27}{10}=2\dfrac{7}{10}\)
\(\dfrac{15}{12}=1\dfrac{3}{12}\)
\(\dfrac{13}{4}=3\dfrac{1}{4}\)
15 \(\frac{27}{25}\)bằng\(\frac{402}{25}\)
7\(\frac{33}{201}\)bằng\(\frac{1440}{201}\)
\(\frac{2007}{135}\)=14\(\frac{117}{135}\)
\(\frac{17}{12}\)=1\(\frac{5}{12}\)
\(\frac{126}{27}\)=4\(\frac{18}{27}\)
\(\frac{311}{39}\)=7\(\frac{38}{39}\)
a) \(15\frac{27}{25}\)=\(\frac{402}{25}\);\(7\frac{31}{201}\)=\(\frac{1438}{201}\)
b)\(\frac{2007}{135}=14\frac{13}{15}\);\(\frac{17}{12}=1\frac{5}{12}\);\(\frac{126}{27}=4\frac{2}{3}\);\(\frac{311}{39}=7\frac{38}{39}\)
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.
a) 3 và 3/4=3,75
b) 19 và 3/8=19,375
c) 27 và 2/5=27,4
a ) \(0\frac{13}{14}\)
b) \(3\frac{3}{4}\)
c) \(2\frac{5}{11}\)
d) \(5\frac{7}{13}\)
a) \(\frac{13}{14}\)= \(\frac{13}{14}\)
b)\(\frac{15}{4}\)= \(3\frac{3}{4}\)
c) \(\frac{27}{11}\)=\(2\frac{5}{11}\)
d)\(\frac{72}{13}\)=\(5\frac{7}{13}\)
Hok tốt ^^ Đúng k mik nhé !!!
