PLEASE NEED HELP ASAP

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?

Answer 1

120/100 a = 80/100 b

12/10 a = 8/10 b

10 (12/10) a = 10 (8/10) b

12a= 8b

3a= 2b

a+b in terms of a

b = 3/2×a

a+ 3/2×a = 5/2×a

a+b in terms of b

a = 2/3×b

b + 2/3.b = 5/3×b

Answer 2

120% of a
80% of b

120% = 120/100 =1.2
80%= 80/100 = 0.8

1.2a=0.8b | ÷1.2
1a = 2/3 b

1.2a=0.8b | ÷0.8
1b=1.5a


(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
