Question

Compare as frações : >,< ou =
A) 3/8 ---- 4/8
B) 13/15----- 27/30
C) 2/3 ---- 20/30
D)21/36----7/12
E)1/7---1/12
F)7/2 ----49/14
G)9/8----22/22
H)7/15 ---- 17/25
2) Escreva em ordem crescente :
7/8, 4/7 ,6/5,1/3,3/4,2/5,5/2

Answer 1

A)3/8=0,375   //   4/8= 0,5, portanto, 3/8<4/8
B)13/15=0,87   //   27/30=0,9, portanto: 13/15<27/30
C)2/3=0,66 (Multiplique por 10) = 20/30, portanto, 2/3=20/30
D)21/36 (Divide por 3) = 7/12, portanto, 21/36=7/12
E)1/7=0,14   //   1/12=0,08, portanto, 1/7>1/12
F)7/2 (Multiplique por 7) = 49/14, portanto, 7/2=49/14
G)9/8=1,12   //   22/22=1, portanto, 9/8>22/22
H)7/15=0,46   //   17/25=0,68, portanto, 7/15<17/25

2)
7/8=0,87
4/7=0,57
6/5=1,20
1/3=0,33
3/4=0,75
2/5=0,40
5/2=2,50

1/3 < 2/5 < 4/7 < 3/4 < 7/8 < 6/5 < 5/2



Espero ter ajudado =)
