we know that a is +ve hence the expression 3a is +ve since +ve * +ve = +ve for the same reason 2b is also +ve and equal to 3a.

a:b = 2:3 here a= 2, b= 3
sub in Quantity A = a+5/b=5

= 2+5/3+5

= 7/8 = 0.87

Quantity B = 1 ( B is greater ) 0.87 < 1

a is positive.

Quantity A
Quantity B
\(\frac{a+5}{b+5}\)
1


A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.



GIVEN: a : b = 2 : 3
In other words: a/b = 2/3

NOTE: Since a is positive, we can be certain that b is also positive

From here, we can solve this question using matching operations

Given:
Quantity A: \(\frac{a+5}{b+5}\)
Quantity B: 1

Since b is positive, we know that b+5 is positive, which means we can safely multiply both quantities by b+5 to get:
Quantity A: a + 5
Quantity B: b + 5

Subtract 5 from both quantities to get:
Quantity A: a
Quantity B: b

Divide both quantities by b to get:
Quantity A: a/b (which we already know is equal to 2/3)
Quantity B: 1

Answer: B

Cheers,
Brent
