The two equivalent ratios are:
** 2:2**
** and 5:5** ;
In mathematics, a **ratio **is a relationship between two numbers that indicates how many times the first number contains the second. Put another way, a ratio says how much of one thing there is compared to another thing.
We can express ratios in different ways.
a) We Use the the symbol : to separate the values. For instance:
4:1
**b) We can use the word to. **For instance:
3 to 1
c) We can write it like a fraction. For instance:
1 4
____________________________________________
Since the problem establishes to write two ratios that are equivalent to **1:1. **From the Figure below there is 1 red square to 1 blue square. So, writing the new ratios we have:
First.
**2:2 **is equivalent to **1:1, **that is the ratio is also 1 red square to 1 blue square, even though there are more squares. You can see this in the Figure below.
Second.
**4:4 **is equivalent to **1:1. **As in the previous statement the ratio is also 1 red square to 1 blue square, even though there are four red squares and four blue squares as illustrated in the Figure.
To find two ratios equivalent to 1:1, you can multiply both numbers by the same value. For example, 2:2 and 3:3 are both equivalent to 1:1. These show that the relationship between the two quantities remains the same, regardless of how large both numbers are.
