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

Answer:
The answer to your question is Angelica 19, her mom = 11
Step-by-step explanation:
Data
Angelica has 8 more than her mother
total number of shoes = 30 pairs
The Number of pairs Angelica has = a = ?
The Number of pairs her mother has = m = ?
Process
1.- Write two equation that help to solve this problem
a = m + 8 Equation l
a + m = 30 Equation ll
2.- Solve the system of equations by substitution
Substitute equation l in equation ll
(m + 8) + m = 30
-Solve for m
m + 8 + m = 30
2m = 30 - 8
2m = 22
m = 22/2
m = 11
3.- Find a
a = 11 + 8
a = 19
4.- Conclusion
Angelica has 19 pairs of shoes and her mom has 11
