Answer:
3 : 2
Explanation:
We are asked to calculate as a ratio 9 nickels to 3 dimes reduced to lowest terms.
One nickel means $0.05 and one dime means $0.10.
So, 9 nickels is equal to $(0.05 × 9) = $0.45
And 3 dimes is equal to $(0.10 × 3) = $0.30
Therefore, the ratio will become 0.45 : 0.30 ≡ 3 : 2 (Answer)
