Step-by-step explanation:
The last part of your question isn't well written but let me rewrite based on what I think should be there.
Ala make 19 cookies in 30 min and Jane make 30 in 45 min so what is total cookies made by both in 1.5 hour?
Since Ala makes 19 cookies in 30 minutes. The number of cookies made in 1.5 hours will be:
= 19 × 1.5hours/30 minutes
= 19 × 90min/30min
= 19 × 3
= 57 cookies
Jane make 30 in 45 min. The number of cookies made in 1.5 hours will be:
= 30 × 1.5hours/45minutes
= 30 × 90minutes/45minutes
= 30 × 2
= 60 cookies
The total cookies made by both will then be:
= 57 + 60
= 117 cookies
Note that 1.5 hours = 1.5 × 60 minutes = 90 minutes
