#sqrt(49)#, #color(red)cancel(1.6)#, #color(red)cancel(-3/7)#, #-55#, #color(red)cancel(36/9)#

By definition, an integer is any whole number that is not a fraction.

With this, let's go down the list:

*#sqrt(49)#*

We know that #sqrt(49)# simplified is 7 which is a whole number.

#1.6#

#1.6# is not a whole number to we can rule this out.

#-3/7#

#-3/7# is a fraction so this one is not an integer.

#-55#

#-55# is a whole number and not a fraction so this is an integer.

#36/9#

Once again, we can see #36/9# is a fraction, so it's not an integer.

Final answer:

#sqrt(49)#, #color(red)cancel(1.6)#, #color(red)cancel(-3/7)#, #-55#, #color(red)cancel(36/9)#
