Answer: 9/20
Step-by-step explanation:
1) Find the Least Common Denominator (LCD) of 3/4 and 3/10. In other words, find the Least Common Multiple (LCM).
The LCM would be 20
2) Make the denominators the same as the LCD
3*5/4*5 - 3*2/10*2
3) Simplify
15/20 - 6/20
4) Now combine both fractions because they have the same denominator.
ANS= 9/20
