b) 0,6 * 2/5+1,5:1 2/3=

c) 1,125 - 2 1/4 : 2 4/7=

d) ( 2 2/5 + 1,2) : 2 4/7=

e) 2,8 - 1,8 : 1 1/5=

f) 6,3 + 0,7 * 1 3/7=

Answer 1

a)5/9 * 9/2 - 6/10 * 5/3 = 5/2 - 2 =1/2
b)6/10 * 2/5 + 3/2 : 5/3 = 6/25 + 9/10=24/100 + 90/100 = 114/100
c)9/8 - 9/4 : 18/7= 9/8 - 7/8 =2/8=1/4
d)(12/5 + 6/5) : 18/7 = 18/5 : 18/7 = 7/5
e)28/10 - 18/10 : 6/5= 28/10 - 3/2 = 28/10 - 15/10 = 13/10
f)63/10 + 7/10 * 10/7 = 63/10 + 1 = 73/10 =  7,3
