Hi!
First, let's find the LCD of the denominators. (5, 4, and 2)
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
4, 8, 12, 16, 20
5, 10, 15, 20
Now we have to change all of the numerators to match the denominators.
Since 5 goes into 20 four times..
2 x 4 = 8
8/20
Since 4 goes into 20 five times...
3 x 5 = 15
15/20
Since 2 goes into 20 ten times...
1 x 10 = 10
10/20
Our new fractions are..
8/20+15/20+10/20=?
Now just add the numerators.
33/20
If you want to simplify it to a mixed number, your answer is 1 13/20
If you want to keep it as a fraction, it's already in simplest form. So the answer is 33/20
Hope this helps! :)
Given 736 hours, we are asked to find how many days are in it. This can be seen below.
Let x be the number of days in 736 hours. Since there are 24 hours in a day, we would have;
Thus,
Answer: 30.7
You can use side-angle-side postulate
36/3 =12
Sorry there isn't much work to show, not sure what can be shown
