Answer:
The next time she will have both meetings on the same day again is 24 days time
Step-by-step explanation:
The given information are;
The frequency of the Junior Optimist club meeting = Every 3 days
The frequency of the Drama club meeting = Every 8th day
The club meeting Anna will attend today = Both meetings
The next time she will have both meetings on the same day again is given as follows;
The next time she will have both meetings on the same day again = The number of days the complete cycles of both meetings will coincide = The product of the cycles of both meetings
The next time she will have both meetings on the same day again = 8 × 3 = 24 days
The next time she will have both meetings on the same day again = 24 days time.
4/5 + 11/12
To add fractions they must have the same denominator (bottom number)
Let's change the denominators of our fractions to something else.
This new denominator should be divisible by the old ones (5 and 12)
Let's just use 5 × 12 = 60 as our denominator.
To get 4/5 to a denominator of 60--
The top and bottom of any fraction can be multiplied by the same number to get an equal fraction and essentially change the denominator.
We want to multiply 5 by something to get 60...
let's multiply the top and bottom of 4/5 by 12.
4/5 = 48/60
Now, 11/12.
We need to mulitply the top and bottom by 5 to get the bottom to 60.
55/60
Now instead of
4/5 + 11/12
we have
48/60 + 55/60
Let's add the numerators (top numbers).
(48+55)/60
103/60
If you need your answer as a mixed number:
103/60
60/60 + 43/60
Answer:
the equation is 140÷42 and the answer is 4
Answer:
There are 12 red fish, 19 orange fish
Step-by-step explanation:
Let y rep amount of red fish
y + 7 = Amount of orange fish
y + y + 7 = 31
2y = 31 - 7
2y = 24
y = 12
Then
y + 7
12 + 7 = 19
