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
∠YVZ = 180 - 52 - 43 - 38 (Angles on a straight line add up to 180 degrees so if we try to find an unknown angle on the straight line, we need too subtract all the other angles from 180 degrees)
