Answer 2

Given,

• The rational number 5/11 is given.

To find,

• Four equivalent rational numbers for 5/11

Solution,

The four equivalent rational numbers for 5/11​ are 10/22, 15/33, 20/44, and 25/55.

We can simply find the equivalent rational number for 5/11 by multiplying and dividing the rational number by the same number.

The equivalent rational numbers are defined as the numbers whose simplest forms are the same.

Multiplying and dividing 5/11  by 2, we get

                               5/11 * 2/2 = 10/22

Similarly, multiplying and dividing 5/11 by 3, 4, and 5 respectively, we get

                               5/11 * 3/3 = 15/33

                               5/11 * 4/4 = 20/44

                               5/11 * 5/5 = 25/55

Hence, the four equivalent rational numbers for 5/11 are ​10/22, 15/33, 20/44, and 25/55.
