One way to solve: (4/5) ÷ (9/10) = (4/5) * (10/9) = 40/45, simplifies to 8/9. To divide, just multiply by the reciprocal [reciprocal of 9/10 is 10/9]

Nine and two thirds divided by four and five fifths = 114/15
1 tenth
It is: -3/5 divided by 9/10 = -2/3
3.8 + 2.9 = 6.7
nine tenths is 90% and four fifths is 80% so nine tenths is bigger

Yes
Nine and two thirds divided by four and five fifths = 114/15
1 tenth
It is: -3/5 divided by 9/10 = -2/3
3.8 + 2.9 = 6.7
I checked it. It equals to...45/4
Thirteen tenths
4.7
no
Nine tenths plus two fifths minus one fourth is equal to 1.05
