To find equivalent ratios just factor the same number to both numerator and denominator. I will make the ratios simple by multiplying 2/2 and 3/3 to the originals. To check, set as fraction and cross multiply and you should have the same number. I will show you how to check by doing it to the first ratio.
8:5 16:10 24:15
Check:
8/5 = 16/10
(8)(10)=(5)(16)
80=80
8/5=24/15
(8)(15)=(5)(24)
120=120
4:19 8:38 12:57
6:23 12:46 18:69
This is the concept of proportionality, given that m is directly proportion to y and n and inversely proportional to p^2. We are required to find what happens to m when y is quadrupled, p is tripled and n is multiplied by 5;
From the equation;
m=(yn)/p^2
when:
y is quadrupled we get 4y
p is tripled we get 3p
n is multiplied by 5 we get 5n
thus the new value of m will be:
m=(4y*5n)/(3p)^2
m=(20yn)/9p^2
m=(20/9)(yn/p^2)
that means that m will be increased bby 20/9
