Answer:
30 times
Explanation:
Jeanna : Haylee = 2 : 5
The number of times Haylee babysits in one month is unknown, so it is represented as x.
Write a new ratio to represent the scenario
2 : 5 = 12 : x
Ratios can be written as fractions
Rewrite
2/5 = 12/x
Cross multiply (numerator * denominator / numerator * denominator)
2x = 60
x = 30
Haylee babysat 30 times that month
Hope this helps :)
