Given t is a positive integer and 4/7 = t/s --> s = 7t/4.

Substitute away s in A: 7t/4 vs B: 7

Multiply by 4/7 to both sides: A: t vs B: 4

t can be either less than 4 or greater than 4.

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

GIVEN: 4/7 = t/s

There are infinitely many values of t and s that satisfy the condition that 4/7 = t/s
Consider these two sets of values:

t = 4 and s = 7
In this case, we get:
Quantity A: 7
Quantity B: 7
Here, the two quantities are EQUAL

t = 8 and s = 14
Notice that t/s = 8/14 = 4/7
In this case, we get:
Quantity A: 14
Quantity B: 7
Here, Quantity A is GREATER

Cheers,
Brent

4/7 can be written as 4/7 or 8/14 or 12/21 so on..

In first case s=7 and in fllowing casses s is greater than 7. Hence the answer
