There'll be 5 parents that'll go to the museum
Let the number of parents that will go to the museum be represented by x.
Based on the information given, the equation to use will be:
15/75 = x/25
Cross multiply
75 × x = 15 × 25
75x = 375
Divide both side by 75
75x/75 = 375/75
x = 5
Therefore, there'll be 5 parents that'll go to the museum.
