6. Find 4 ratios equivalent to 25%
30% = 3/10 = 6/20 = 12/40 = 24/80
To find ratios equivalent to a given percentage, you need to convert the percentage into a fraction or a ratio. Here's how you can do it:
5. Find 4 ratios equivalent to 30%:
Step 1: Convert 30% into a fraction. To convert a percentage into a fraction, divide the percentage by 100. So, 30% is equal to 30/100, which simplifies to 3/10.
Step 2: To find ratios equivalent to 30%, you can multiply or divide both the numerator and denominator of the fraction by the same number, as long as it does not change the value of the fraction. Let's explore a few possibilities:
- Multiply both the numerator and denominator by 2: 3/10 * 2/2 = 6/20
- Multiply both the numerator and denominator by 3: 3/10 * 3/3 = 9/30
- Multiply both the numerator and denominator by 4: 3/10 * 4/4 = 12/40
- Multiply both the numerator and denominator by 5: 3/10 * 5/5 = 15/50
So, 4 ratios equivalent to 30% are 6/20, 9/30, 12/40, and 15/50.
6. Find 4 ratios equivalent to 25%:
Step 1: Convert 25% into a fraction. 25% is equal to 25/100, which simplifies to 1/4.
Step 2: Similar to the previous example, you can multiply or divide both the numerator and denominator of the fraction by the same number. Here are a few possibilities:
- Multiply both the numerator and denominator by 2: 1/4 * 2/2 = 2/8
- Multiply both the numerator and denominator by 3: 1/4 * 3/3 = 3/12
- Multiply both the numerator and denominator by 4: 1/4 * 4/4 = 4/16
- Multiply both the numerator and denominator by 5: 1/4 * 5/5 = 5/20
So, 4 ratios equivalent to 25% are 2/8, 3/12, 4/16, and 5/20.
