Taking the question as asked,
3 7/12 + -2 4/5 =
3 7/12 - 2 4/5 =
3 35/60 - 2 48/60 =
215/60 - 168/60 =
47/60
it is 2 and four fifths
Four-fifths. 2/5 + 2/5 = 4/5.
2. 3/5
1/2 or one half
I think it's 1 and 2/5
Four fifths (4/5) = 0.8 Eight twelves (8/12 = 2/3) = approx. 0.67. So, yes, 4/5 is greater than 8/12.
4/5 plus 2/10 = 1
1 2/5
2/5 + 4/5 = 6/5 or 1 1/5
four and three twentieths :)
2 fourths times four fifths is 2 fifths.
3.8 + 2.9 = 6.7
