Question

Arrange 5/7 3/8 1/2 from least to greatest

Answer 1

Explanation:

`(5)/(7) = (5 * 8)/(7 * 8) = (40)/(56) \\ \\ (3)/(8) = (5 * 7)/(8 * 7) = (21)/(56) \\ \\ (1)/(2) = (1* 28)/( * 28) = (28)/(56) \\ \\ \because 21 < 28 < 40 \\ \\ \therefore \: (21)/(56) < (28)/(56) < (40)/(56) \\ \\ \huge \red{ \boxed{\therefore \: (3)/(8) < (1)/(2) < (5)/(7) }}`

Answer 2

Explanation:

5/7=0.71428571...

3/8=0.375

1/2=0.500

0.375<0.500<0.714

so 3/8<1/2<5/7
