Five and seven eighths
Converting the fractions to eights we get: 1 + one eight + two eights, which gives us 1 and three eights as the answer.
It is ten eights, or one and two eights or one and a quarter or 1.25 as a decimal.
Two fifths
One and a half is twelve eights.plus five eights, is seventeen eights. That is two and one eighth in total, or 2.125 in decimal.

Three and three eights
The final answer would be three and three-eighths. Here's how to solve it mentally.You have to set their denominators [bottom numbers] equal. So, keep seven eights, since two ["half"] goes into eight, but you must make 2 and a half into 2 and four eights, because four is half of eight. Pretend for a minute that the four eights isn't there. So, 2 and seven eights. Then, add one from the four eights, so that it will now be 3., and so that the four eights is now three eights. So, 3 and three eights.Sorry. I'm not very good at explaining, but I hope that helped. ^^"
