Answer:
6/25
Step-by-step explanation:
I turned all of it to decimals and percentages.
7/10 = 70%
4/5 = 0.8
70% of 0.8 is 0.56.
0.56 = 14/25
So 4/5 - 14/25 = 6/25
Im not 100% sure this is correct but thats how I would do it it.
-27 = 3x/10
Times 10 for both sides
-270 = 3x
x = -270/3
x = -90
Your number is 8, if u multiply 8 by 3 u get 24 , plus 8 is 32 , which is 4x8
