Question

а)3/2 : 2=?
б)1 4/5 : 4=?
в)171 1/4 : 1=?
г)2/3 : 3=?
д)-17 1/2 : 7=?
е) 1 3/7 : (-2)=?

Answer 1

3/2 : 2 = 3/2 * 1/2 = 3/4
1 4/5 : 4 = 9/5 * 1/4 = 9/20
171 1/4 : 1 = 171  1/4
2/3 : 3 = 2/3 * 1/3 = 2/9
-17 1/2 : 7 =  -35/2 * 1/7 = -35/14 = -2  1/2 =  -2,5
1 3/7 : (-2) = 10/7 * (-1/2) = -5/7
