Remember that percent just means "out of 100", so 116% is 116 out of 100:
![\frac{116}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B116%7D%7B100%7D)
To simplify, you just divide each number by numbers that go into each:
![\frac{116}{100}\div\frac{4}{4}=\frac{29}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B116%7D%7B100%7D%5Cdiv%5Cfrac%7B4%7D%7B4%7D%3D%5Cfrac%7B29%7D%7B25%7D)
So, 116% in simplified fraction form is 29/25.
Answer:
750kmph
Step-by-step explanation:
Average is sum of all parts divided by the number of parts.
Let Stot be average speed for total trip (800kmph).
Let S1 be speed for first quarter of trip (950kmph).
Let S2, S3, and S4 be the speeds of each of the remaining quarters respectively.
Let Sans be the average speed for the remaining three quarters of the trip (a.k.a. The Answer!).
Stot = (S1 + S2 + S3 + S4) / 4
800kmph = (950kmph + S2 + S3 + S4) / 4
3200kmph = 950kmph + S2 + S3 + S4
3200kmph - 950kmph = 2250kmph = S2 + S3 + S4
Divide both sides by 3.
2250kmph / 3 = (S2 + S3 + S4) / 3 = Sans
Sans = 750kmph
I believe the answer is D
Answer:
3 1/8 or 3.125.
Step-by-step explanation:
First you would change 1 1/4 to 5/4. Then you would make a proportion of 5/4 or I like to use decimals, 1.25, over 8. Your proportion would look like: 1.25/8 = x/20. Then cross multiply 1.25 and 20 then divide your product by 8. Your final answer is 3.125 or 3 1/8. Hope this helps!
