Divide both numbers by 15.

15 / 15 = 1
75 / 15 = 5

1 : 5

Answer:

Option A is correct.

Given ratio in lowest form is, 1 : 5

Step-by-step explanation:

Ratio states that it is a relationship between two things when it is expressed in numbers or amounts.

i,e a to b = a: b = [tex]\frac{a}{b}[/tex]

Given : The given ratio 15 : 75

by definition of ratio,

[tex]\frac{15}{75}[/tex]

Divide both numerator and denominator by 15 we get;

[tex]\frac{\frac{15}{15}}{\frac{75}{15}}[/tex]

Simplify:

[tex]\frac{1}{5}[/tex]

Or we can write this ratio as 1 : 5.

Also, check that we can't divide any more numbers into both terms other than 1.

Therefore, the ratio 15 : 75 in lowest term is, 1 : 5
