23: 21 25: 1
Step-by-step explanation:
<u>Question 23</u>:
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 answer:
20+1= 21
Answer: 21
