Answer:
Multiplying a number by n is equivalent to dividing it by 1/n.
Step-by-step explanation:
We generalise for any whole number n.
In this problem, you add 21 and 29. That results in 50 and you can either:
1. Divide 29 by 50 and multiply 100. 29/50= .58 * 100= 58% or
2. Since percentage is based on 100 and the denominator is 50, multiply the top and bottom by 2 like so.
29 x 2 = 58
--- -- ----- so that makes your percentage 58.
50 x 2 = 100
Hope this is clear enough.
C = 2 pi r
C = 2 x 3.14 x 5
C = 31.4 yd
A = pi r^2
A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 yd^2
