Answer:

See a solution process below:

Explanation:

First, multiply each fraction by the appropriate form of #1# to put the fractions over a common denominator without changing the value of the fractions:

#(2/2 xx 2/15) - (3/3 xx 1/10) =>#

#(2 xx 2)/(2 xx 15) - (3 xx 1)/(3 xx 10) =>#

#4/30 - 3/30#

Now, subtract the numerators over the common denominator:

#4/30 - 3/30 =>#

#(4 - 3)/30 =>#

#1/30#
