( 5/7 - 1/2 ) : ( 2/4 x 1/4 ) =

( 3 1/2 + 4) x 1/4

( 5 : 1 2/3 + 6 1/2 ) x 2

Answer 1

(5/7 - 1/2) : (2/4 * 1/4) = (10/14 - 7/14) : (2/16) =  3/14 * 16/2 = 3/14 * 8 = 24/14 =
= 1 10/14 = 1 5/7

(3 1/2 + 4) * 1/4 = 7 1/2 * 1/4 = 15/2 * 1/4 = 15/8 = 1 7/8 

(5 : 1 2/3 + 6 1/2) * 2 = (5 : 5/3 + 6 1/2) * 2 = (5 * 3/5 + 61/2) * 2 = 
= (3 + 6 1/2) * 2 = 9 1/2 * 2 = 19/2 * 2 = 19/4 = 4 3/4
