To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the least common multiple ( LCM ) of the denominators which is equal to the least common denominator ( LCD ). You can then rewrite each term as an equivalent fraction with the LCD .
TanB has a ratio of 8/15 because it is opposite over adjacent.
3/5 divided by 1/2 equals 6/5 or 1 and 1/5!
(My method- Keep 3/5, change the division sign to a multiplication sign, and flip 1/2 to 2/1. Multiply strait across and you get 6/5! 5 can go into 1 one time and that leaves 1/5! So your answer is 1 and 1/5! Hope it helps!)
Answer:
d is the answer ok :)
Step-by-step explanation:
9.2r + 5.514 = 158.234
since your solving for r subtract 5.514 from both sides
9.2r = 158.234 - 5.514
9.2r = 152.72
then divide both sides by 9.2
r = 152.72/9.2
r = 16.6
