Answer:

The answer to your question is 64/100 and 65/100

Step-by-step explanation:

Data

Common denominator of   16/25 and 13/20

Process

1.- Find the least common factor of 25 and 20.

                            25      20      2

                            25      10       2

                            25        5       5

                              5         1       5

                               1

   L.C.F. = 2 x 2 x 5 x 5 = 100

2.- Convert each fraction to the denominator 100

           100 / 25 = 4

            16/25 = (16 x 4) / 100

                     = 64/100

            100 / 20 = 5

            13/20 = (13 x 5)/100

                      = 65/100

Step-by-step explanation:

List of multiples of 25: 0, 25, 50, 75, 100, 125, 150, ...

List of multiples of 20: 0, 20, 40, 60, 80, 100, 120, 140, ...

LCM(25, 20) = 100

100 = (25)(4)

100 = (20)(5)

[tex]\dfrac{16}{25}=\dfrac{(16)(4)}{(25)(4)}=\dfrac{64}{100}\\\\\dfrac{13}{20}=\dfrac{(13)(5)}{(20)(5)}=\dfrac{65}{100}[/tex]
