Exercise #1

Using 3 bags of corn kernels, one can make 21 small packages of popcorn. Which of the cases represent the same ratio

Step-by-Step Solution

To solve this problem, we'll proceed with the following steps:

  • Step 1: Simplify the initial ratio given in the problem.
  • Step 2: Simplify the ratios of each choice and compare them with the simplified initial ratio.

Let's go through these steps in detail:

Step 1: Simplifying the ratio given in the problem:

The initial ratio is 3 bags of corn to 21 packages of popcorn. We can express this as the ratio 321\frac{3}{21}.

To simplify, divide both the numerator and the denominator by their greatest common divisor, which is 3:

3÷321÷3=17\frac{3 \div 3}{21 \div 3} = \frac{1}{7}.

So, the simplified ratio is 1 bag of corn to 7 packages of popcorn.

Step 2: Now, let's simplify each of the given choices to see which one matches the simplified ratio of 17\frac{1}{7}.

  • Choice 1: 6 bags of corn to 3 packages of popcorn
    Expressed as a ratio: 63=2\frac{6}{3} = 2, which simplifies to 2, not 17\frac{1}{7}.
  • Choice 2: 1 bag of corn to 4 packages of popcorn
    Expressed as a ratio: 14=0.25\frac{1}{4} = 0.25, not 17\frac{1}{7}.
  • Choice 3: 1 bag of corn to 7 packages of popcorn
    This ratio is clearly already 17\frac{1}{7}, the same as our simplified initial ratio.
  • Choice 4: 2 bags of corn to 10 packages of popcorn
    Expressed as a ratio: 210=15\frac{2}{10} = \frac{1}{5}, not 17\frac{1}{7}.

Comparing each of the choices to the simplified ratio 17\frac{1}{7}, we find that Choice 3 is the correct match.

Therefore, the solution to the problem is 1 bag of corn, 7 packages of popcorn, which corresponds to Choice 3.

Answer

1 bag of corn
7 packages of popcorn

Exercise #2

What is the reduced ratio of the ratio 8:6 8:6 ?

Step-by-Step Solution

To solve this problem, let's reduce the ratio 8:6 8:6 to its simplest form.

First, we need to determine the greatest common divisor (GCD) of the numbers 8 and 6. The divisors of 8 are 1, 2, 4, and 8. The divisors of 6 are 1, 2, 3, and 6. The greatest common divisor shared by both 8 and 6 is 2.

Next, we simplify the ratio by dividing both terms of the ratio by their GCD:

  • Divide 8 by 2: 82=4 \frac{8}{2} = 4
  • Divide 6 by 2: 62=3 \frac{6}{2} = 3

Thus, the ratio 8:6 8:6 simplifies to 4:3 4:3 .

Therefore, the reduced ratio of the given ratio is 4:3 4:3 .

Answer

4:3 4:3
