five and a half=5.5 four fifths=.8 since one divided by five is .2 and four .2's (4x.2)=.8 5.5x.8=4.4, or four and 2 fifths four and two fifths is the answer.
One and three fifths.
It is: 4/5 times 10 = 8
(4/5) times 2 = 8/5; eight-fifths; or 1.6
It is: 2/3 times 4/5 = 8/152/3 x 4/5 is 8/15.
4/5 x 10 is 8.
8/5 x 7/2 = 56/10 = 5.6 or five and three fifths
four fifths times 8 equals six and two fifths
5/2 x 5/4 = 25/8
4/5 x 5/8 is 1/2.
4/5 of 5/8 = 4/5 x 5/8 = 4/8 x 5/5 = 1/2 x 1 = 1/2
8*.5=4
