1227.
7/10 + 5/17 = 169/170
The answer = 3440
236+710 = 946. Rounded to 2 significant digits, that is 950, rounded to one sd, it is 900.
707.
710 + 55 = 765
710 + 13 = 723
710 + 35 = 745
6 + 710 = 716
There are 3725 of them because 3725/5 = (35+710) => 745
If you add 25 to 710, you will get 735.
The sum of the equation - 990 + 880 +90 +790 +690 + 20, is found as follows;990 + 880 +90 +790 +690 + 20= (990 + 880) + (90 +790) + (690 + 20)= ( 1870 ) + (880 ) + ( 710 )= 3460Answer = 3460
