Because the number is even, then the number of possible combinations will be: 110/2 = 55 let's consider a simpler example, the number: 10, then we have: 10+0, 9+1, 8+2, 7+3, 6+4, which is equal to 10/2 =5 combinations. Note: We are not considering permutations between the elements of the sum therefore 10+0, 0+10 counts as one combination.
Answer:
7% of 78 is 5.46
Step-by-step explanation:
Given number = 78
We have to find 7% of 78 So:
= 7/100 * (78)
= 0.07 (78)
= 5.46
So 7% of 78 is 5.46
i hope it will help you!
3 over 4 is already simplified. 15 over 12 is 5 over 4. If you are having trouble with the concept, www.ducksters.com/kidsmath/fractions_reducing_simplifying.php is a great guide
