Answer=250 grams
To solve this, we need to convert the 3 kg that Ali purchased into grams
1kg=1000g
3kg*1000=3000g
Alis mandarin oranges weighed 3000 grams
Mia-Ali=3250-3000=250grams
Mia purchased 250 more grams than Ali did
Here's what I did and I checked it So it is correct!!
![\frac{7}{28} = \frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B28%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20)
![\frac{1}{4} = 0.25](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%3D%200.25)
25% is your answer.
![28 \times 25\% = 7](https://tex.z-dn.net/?f=28%20%5Ctimes%2025%5C%25%20%3D%207)
