We can make everything have the same denominator so we can add, subtract, and compare them:
The common denominator between 2, 4, and 8, is 8.
7/8 = 7/8
1/2 = 4/8
1/4 = 2/8
The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:
Laura : 7/8
Daniel: 4/8
Annabelle: 2/8
4/8 + 2/8 = 6/8
So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:
7/8 > 6/8.
This means that Laura rowed more than Daniel and Annabelle.
Answer:
About 3 times faster
Step-by-step explanation:
Cheetah's speed = 110 km / hr
World 100m sprint record :
Speed of sprinter :
Distance / time
100 m / 9.58s
= 10.438413 m/s
Convert Cheetah's speed to m/s
110 km/hr = (110 * 1000)m / (60 * 60 s)
= 110000 m / 3600 s
= 30.55555 m/s
Number of times cheetah is faster than sprinter :
30.55555 m/s ÷ 10.438413 m/s
= 2.927 times
It belongs to the integer group
A. Since the ribbons come in rolls of 15, we need groups of 15 yards. Since we are told that we have 322 yards. We have to find a way to express this number into groups of 15. To do that we can simply divide. 322 /15 = 21.466... since we can’t have one fourth of a role, we have to buy a whole one to be able to get that .4. So, Quincy needs 22 roles.
B. Twice means two times something. So all you do is multiply 322( the number of yards Quincy needs) times 2 = 644. Alice needs 644 yards of ribbon.
C. All you have to do is break 285 yards into 3 groups so: 285/3= 95. So, Elena needs 95 yards of yellow, 95 yards of red, and 95 yards of blue.
Hope this helped and pls mark as brainliest!
