That is the surface area of the frame.

Then, if area of circle radius is 100%, the % of face of the clock is:

Solve 15 3/4 ÷ 2 5/8 × 5 5/6 ÷ 8 2/5​
fenix001 [56]

Answer:

4 1/6

Step-by-step explanation:

15 3/4 ÷ 2 5/8 × 5 5/6 ÷ 8 2/5

assuming this order of operations:

(15 3/4 ÷ 2 5/8) × (5 5/6 ÷ 8 2/5)

63/4 x 8/21 = 505/84 = 6

35/6 x 5/42 = 175/252

6 x 175/252 = 1050/252 = 4 42/252 = 4 1/6

The ratio of men to women in a certain factory is 3 to 4. There are 210 men.
WARRIOR [948]
There are 490 workers

3/4 = 210/x
Cross multiply, 210x4 and 3x
You're then left with 3x = 840, divide both sides by 3
This answer is 280 and represents the amount of female workers

Then just add 210 and 280, your answer is 490. Hope that helps!
