Answer:
8/30 (Simplified answer: 4/15)
Step-by-step explanation:
Find common denominators. Note the what you do to the denominator, you do to the numerator.
Multiply 10 to both the denominator & numerator of 2/3, and multiply 3 to both the denominator & numerator of 4/10
(10/10)(2/3) - (3/3)(4/10)
Simplify.
(20/30) - (12/30)
Simplify. Combine the terms
(20/30) - (12/30) = (20 - 12)/30 = 8/30
Simplify the fraction
(8/30)/(2/2) = 4/15
