# 8 2/5# or #42/5#

Explanation:

Write 8.4 as a fraction.

The first place to the right of the decimal is the tenths place, so

#8.4 = 8 4/10#

Reduce #4/10# by dividing the numerator and denominator by #2#

#4/10 = 2/5#

#8.4 = 8 4/10 = 8 2/5#

#8 2/5# can also be written as an improper fraction.

Multiply the whole number #8# by the denominator #5# and add the product to the numerator #2#.

#8 *5= 40# then #40 +2 = 42#

#8.4 = 8 4/10 = 8 2/5= 42/5#
