Answer 1

Answer:

The ratio

30

45

is not in simplest terms (meaning the numerator and denominator have nothing in common), so to find a ratio equivalent, you must reduce the fraction.

So first, you must think to yourself, what do

30

and

45

have in common? Since they both have

5

in common, you would need to divide

30

by

5

, and

45

by

5

.

30

÷

5

45

÷

5

You are left with the fraction or ration

6

9

, which is equivalent to

30

45

. However, this can be reduced even more, since

6

and

9

both are divisible by

3

.

6

÷

3

9

÷

3

Now, your final answer is

2
