Question

please help me with a proper solution

Answer 1

in 1 day,
poppy eats = 4 1/2 = 9/2 pouches
treacle eats = 6 1/2 = 13/2 pouches

They both eat = 9/2 + 13/2 = (9+13)/2 = 22/2 = 11 pouches.

In 1 day, they eat 11 pouches
2 weeks = 2×7 = 14days
In 14 days, they will eat = 14 × 11 = 154 pouches

So, she should buy 154 pouches.
