Bonus Write an equation for the ratio.
a) s:t= 1:5
c) a: b = 1 :
b) f:g= 1:0.5

t = 5s

Step-by-step explanation:

a)  s:t means s/t and 1:5 means 1/5

Therefore the equation would be

s/t = 1/5

Multiply both sides by 5t lcm of 5 and t

5s = t

t = 5s

b)  a:b = 1

a/b = 1

a = b

c)  f:g = 1:0.5

f/g = 1/0.5

Multiply both sides by 0.5g

0.5f = g

g = 0.5f
