23: 21  25: 1

Step-by-step explanation:

Question 23:

1) add the whole numbers together: 15+5=20

2)To add fractions, both need to have the same denominator. Find a number that is a multiple of both denominators (in this case 55)

→ (multiply the numerator and denominator by 5)

→ (multiply the numerator and denominator by 11)

3) add the fractions together

+ = (add the numerators)

4) Turn the improper fraction into a mixed number

Divide 78 by 55. You'll get a whole number and a remainder. The remainder is the new numerator: In this case 55 enters 78 once with a remainder of 23. Therefore:

1

5) Add the whole numbers together to get the final

20+1= 21

21
