1 3/4 x (3 2/3+4 1/5+1 1/3):1 9/14 x 1/7
(3 1/15-1 3/5) x 5-2 x3 2/3+13 2/3 : 5

Answer 1

Answer 2

1 3/4 * (3 2/3+ 4 1/5+ 1 1/3):1 9/14 * 1/7 = 

= 7/4 * (3 10/15 + 4 3/15 + 1 5/15) : 23/14 * 1/7 =

= 7/4 * (8 18/15) * 14/23 * 1/7 =

= 7/4 * 138/15 * 14/23 * 1/7 =

= 1/1 * 69/15 * 7/23 * 1/1 =

= 1 * 3/15 * 7/1 * 1 =

= 21/15 =

= 1 6/15 = 1 2/5

=========================

(3 1/15- 1 3/5) *5-2 *3 2/3+13 2/3 : 5 =

= (2 16/15 - 1 9/15) * 5 - 2 * 9/2 + 41/3 * 1/5 =

= 1 7/15 * 5 - 9 + 41/15 =

= 22/3 - 9 - 2 11/15 =

= 7 5/15 - 9 - 2 11/15 =

= - 1 10/15 - 2 11/15 =

= - 3 21/15 =

= - 4 6/15 = - 4 2/5
