Multiply the numerators Multiply the denominators and divide out any common factors.

#4#

# 8/9 xx 9/2 = ( 8 xx 9)/ (2 xx 9)" "larr 9/9 = 1# so this leaves.

# 8/2 = (2 xx 2 xx 2)/2" "larr 2/2 = 1# so the answer is

# 2 xx2 = 4 #

There is only multiplication so any common factors can be cancelled:

#8/9 xx 9/2#

#=cancel8^4/cancel9 xx cancel9/cancel2#

#=4#
