40+3=43
((40 + 3) + 0.5) + 0.02 = 43.52
2 and 3/5 plus 1 and 3/8 = 13/5 + 11/8 = 104/40 + 55/40 = 159/40 = 3 and 39/40
40 + 24 / 8 -3 +1 = 41
1/3 + 3/40 = 40/120 + 9/120 = 49/120
3/8 + 3/5 = 15/40 + 24/40 = 39/40
40
3( 30 + 40 ) - 6 + 9 3 (70) - 6 + 9 210 - 6 + 9 = 213
40 6 + 46 - 3 - 9 = 40
this equals 818
3/8+4/5 = 15/40+32/40 = 47/40 = 17/40
It is 5.6*101
7/8 + 3/5 = 35/40 + 24/40 = 59/40 or 1 19/40
