Question

Henry is 3 times older than julia. rhianna is 1/2 as old as julia. what formula shows the relationship between henry and rhianna's ages?

Answer 1

h=henry's age
j=julia's age
r=rhianna's age


h is 3 times of j
h=3j

r is 1/2 times of j
r=(1/2)j or
2r=j

so

h=3j
2r=j
sub 2r for j
h=3(2r)
h=6r

henry's age is 6 times of rhianna's age

Answer 2

H = 3J......J = H/3
R = 1/2J....J = 2R

H/3 = 2R <===
