Sure! To find equivalent ratios, you multiply or divide both terms of the original ratio by the same non-zero number. Here are two equivalent ratios for each of the given ratios:

### a. $$ 4 : 5 $$

**Equivalent Ratios:**
1. **Multiply both terms by 2:**
   $$
   4 \times 2 : 5 \times 2 = 8 : 10
   $$
2. **Multiply both terms by 3:**
   $$
   4 \times 3 : 5 \times 3 = 12 : 15
   $$

### b. $$ 2 : 7 $$

**Equivalent Ratios:**
1. **Multiply both terms by 3:**
   $$
   2 \times 3 : 7 \times 3 = 6 : 21
   $$
2. **Multiply both terms by 4:**
   $$
   2 \times 4 : 7 \times 4 = 8 : 28
   $$

### c. $$ 15 : 25 $$

**Equivalent Ratios:**
1. **Divide both terms by 5:**
   $$
   \frac{15}{5} : \frac{25}{5} = 3 : 5
   $$
2. **Multiply both terms by 2:**
   $$
   15 \times 2 : 25 \times 2 = 30 : 50
   $$

These equivalent ratios maintain the same proportion as the original ratios. You can create more equivalent ratios by multiplying or dividing by different non-zero numbers.
