Question

(3 1/2 . 5 5/9 . 45/14) - √25/100
(5/7 + 2/9 + 1/3) : (30/90 . 48/7)
(2/5 + 3/10) : ( 6/7 . 21/48)
(7/15 : 14/30) + (9/40 : 18/20)
(4 2/10 . 2 9/12) : 3/20
(40: 20/6) . (30/4 : 15)

Answer 1

a) (3 1/2 . 5 5/9 . 45/14) - √25/100 
                            125/2 - 1/2 = 124/2

b) (5/7 + 2/9 + 1/3) : (30/90 . 48/7)
                     80/63 : 16/7 = 5/9

c) (2/5 + 3/10) : ( 6/7 . 21/48)
                7/10 : 3/8 = 28/15

d)(7/15 : 14/30) + (9/40 : 18/20)
                       1 + 1/4 = 5/4

e)(4 2/10 . 2 9/12) : 3/20
                 231/20 : 3/20 = 77

f) (40: 20/6) . (30/4 : 15)
              12 . 1/2 = 6
