Final answer:
Jennifer bought a total of 7/8 kg of rice, after adding 3/4 kg of white rice to 1/8 kg of brown rice with a common denominator of 8.
Step-by-step explanation:
Jennifer bought 3/4 kg of white rice and 1/8 kg of brown rice. To find out how many kilograms of rice Jennifer bought altogether, we simply need to add these two quantities:
3/4 kg + 1/8 kgFirst, to add these fractions, they must have a common denominator. The common denominator for 4 and 8 is 8.Converting 3/4 kg to an eighth, we have (3 * 2) / (4 * 2) = 6/8 kg.Now we add 6/8 kg + 1/8 kg = 7/8 kg.
Therefore, Jennifer bought a total of 7/8 kg of rice.
