➷ We know this:
3/7 = 27
You need to find the value of 1/7
To do this, divide by 3
27/3 = 9
1/7 = 9
Multiply this by 7 to get the total number of balls:
9 x 7 = 63
There are 63 balls.

Answer:
6
Step-by-step explanation:
Here, we are told to find the length of EB
Since the chords AB and CD are both 5 units(equidistant) away from the center of the circle, then we can conclude that they are both congruent and thus are equal in length
Now we use a circle theorem to solve for the length EB
The theorem is that a line that joins the center of a circle to a chord makes a perpendicular angle with the chord and splits the chord into 2 equal parts.
Now we can say that; AB = AE + EB so we split 12 into 2 which is 6 units and that is the length of EB
Let x=total crew number
![\frac{x}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B8%7D)
= 0.6666..
cross multiply
![\frac{8}{0.666}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B0.666%7D%20%20)
= x
x=12
12-8 = 4
So there are 4 women in the crew
