Final answer:
To determine which ratio is less than 15, we can compare each simplified ratio to 15 and see which one is smaller. The correct answer is a) 9/15, which simplifies to 3/5 and is less than 15.
Step-by-step explanation:
To determine which ratio is less than 15, we need to compare the ratios to 15 and see which one is smaller.
The options are:
a) 9/15
b) 12/3
c) 24/45
d) 7/9
We can simplify each ratio to their simplest form:
a) 9/15 simplifies to 3/5
b) 12/3 simplifies to 4/1
c) 24/45 can be simplified by dividing both the numerator and denominator by 3, which gives us 8/15
d) 7/9 is already in its simplest form
Comparing each simplified ratio to 15:
a) 3/5 is less than 15
b) 4/1 is greater than 15
c) 8/15 is less than 15
d) 7/9 is less than 15
Therefore, the correct answer is a) 9/15, which simplifies to 3/5 and is less than 15.
