When you multiple fractions, you just multiple numerators and denominators.
10 / 7 × 3 / 8 = (10 × 3) / (7×8) = 30 / 56
Now reduce the fraction:
30 / 56 = 15/28
Final answer: 15/28
Triangle ABC has three sides with these lengths: AB = 9, BC = 40, and CA = 41. What is the value of cos C? A. 9/41 B. 40/9 C. 40/41 D. 9/40
Answers
The answer is letter C which is 40/41. If you draw a triangle the sides found in the cos C is BC which is equal to 40 and the CA which is equal to 41 or the 40/41. It can not be the AB since it is in the opposite side of the cos C.
Just keep in mind that dividing one fraction by another fraction is as much as multiplying the same fraction by an inverse of the second one.
