It could be a lot of things.
As far as a percentage goes, it would be 77.5% which is a solid C in most grading systems.
And 40 - 31 = 9.
31/40 = 31 ÷ 40 = 0.775
16/40 + 15/40 = 31/40
31/40 = 77.5%.
ratio 124 to 40 = 31:10124 : 40 = 31 : 10
9 subtracted from 40 = -31
31/40 = 31 ÷ 40 = 0.775
It is: 31/40 = 0.775
31/40 = 31 divided by 40 = 0.775
16/40 + 15/40 = 31/40
31/40 = 0.775
31/40 = 77.5%.
40 percent of 31 is 12.4
ratio 124 to 40 = 31:10124 : 40 = 31 : 10
31/40
77.5% (31/40)*100 = 77.5%
31 / 40 cannot be further simplified.
3/4 = 0.75 31/40 = 0.775 4/5 = 0.8 3/4 = 30/40 31/40 = 31/40 4/5 = 32/40
