Answer:
11.25
Step-by-step explanation:
4.5 / 2 = 2.25 cups/ cup rice
2.25 x 2 cups of rice = 4.5 cups of water.
5 x 2.25 = 11.25
First do 12-5, which equals 7. Next, subtract 1/10 from 2/5. 2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2. 4/10-1/10=3/10. Now add 7 and 3/10. You will get 7 3/10 as the answer, which is letter C.)
