Please help me with these maths questions

Can someone please give me a hand with these- I'm having a really stressful day and my mind is really blank.

a) 3 over 2 + 5 over 6
b) 4 wholes, 4 over 5 - 1 whole, 1 over 2
c) 2 wholes, 2 over 5 + 4 over 15
d) (3/4)3 (3 being the small squared thing)
e) 2 + 4 over 3 + 3 over 5

I would greatly appreciate if these get answered because its due tomorrow and I've got too much on my plate already.
Could you please also show simple working out for me?
Thanks.

a) 3/2 + 5/6
= 9/6+ 5/6
= 14/6
= 7/3
= 2 1/3

b) 4 4/5 - 1 1/2
= 24/5 - 3/2
=48/10 - 15/10
= 33/10
= 3 3/10

c) 2 2/5 + 4/15
= 12/5 + 4/15
=36/15 + 4/15
= 40/15
= 8/3
= 2 2/3

d) 3/4 * 3
= 3/4 * 3/1
= 9/4
= 2 1/4

e) 2 + 4/3 + 3/5
= 2 + 20/15 + 9/15
= 2+ 29/15
= 3 14/15

i would appreciate top answer as it took me quite a while!

a)3/2+5/6=2/1/3(two and a third)
b)4/4/5-1/1/2=3/1/5(three wholes and a fifth)
c)2/2/5+4/15=2/2/3(two wholes and two thirds)
d)(3/4)^3=27/64(twenty seven over sixty four)
e)2+4/3+3/5=3/14/15(three wholes and fourteen over fifteen)
