White rice cooked = 1 - ¾ = ¼
Brown rice cooked = 1 - ⅜ = ⅝
Equal amount of white rice and brown rice cooked, so the number of units should be the same.
This is a question where you make the numerator the same.
Multiply by 5, White rice = ¼ = 5/20
Brown rice = 5/8
so we can say there are 20 units of white rice , of which 5 units were cooked.
And there were 8 units of brown rice, of which 5 units were cooked.
Total = 8 units + 20 units = 28 units
Cooked = 5 units + 5 units = 10 units
Fraction that was cooked
= 10/28
= 5/14
Brown rice cooked = 1 - ⅜ = ⅝

Thank you! :)
Welcome
See 1 Answer
She bought equal amount of brown and white rice: white rice is half of the total amount of rice,and brown rice is the other half
She had 3/4 of white rice left: she cooked 1/4 of white rice
1/4 of white rice = (1/4 × 1/2) of total amount of rice =1/8
Had 3/8 of brown rice left: cooked 5/8 of brown rice
5/8 of brown rice = (5/8 x 1/2) of total amount of rice = 5/16
Total amount of rice cooked = 1/8 + 5/16 = 2/16 + 5/16 = 7/16
She had 3/4 of white rice left: she cooked 1/4 of white rice
1/4 of white rice = (1/4 × 1/2) of total amount of rice =1/8
Had 3/8 of brown rice left: cooked 5/8 of brown rice
5/8 of brown rice = (5/8 x 1/2) of total amount of rice = 5/16
Total amount of rice cooked = 1/8 + 5/16 = 2/16 + 5/16 = 7/16
Thank you! :)
This is incorrect. The amount of cooked white rice and brown rice is the same, not the total amount of white and brown is the same for each.
Oh okay. Thx!
