Answer:
1. 1/12
2. 4/15
Step-by-step explanation:
1.
3/4 - 2/3
first, you need to set both of the denominators to the same digit by multiplying both the numerator and denominator by the same number
same number meaning the denominator of the other fraction
multiply 3/4 by 3/3
= 9/12 (3x3 and 4x3)
multiply 2/3 by 4/4
= 8/12 (2x4 and 3x4)
9/12-8/12= 1/12
