Question

Ariane feeds her kitten kkk grams of food 222 times in the morning and 222 times in the evening. She feeds her dog ddd grams of food 111 time in the morning and 111 time in the evening.

Answer 1

`4k+2d`

Explanation:

Given:

Grams of food fed to kitten in each time = 'k'

Grams of food fed to dog in each time = 'd'

Number of times kitten is fed in the morning = 2

Number of times kitten is fed in the evening = 2

Number of times dog is fed in the morning = 1

Number of times dog is fed in the evening = 1

Using unitary method,

Grams fed to kitten in 1 time = 'k'

Grams fed to kitten in 2 times =
`2k`

Grams of food fed to dog in 1 time = 'd'

Therefore, the total amount of food to kitten is given as:

Total food to kitten = Food in morning + Food in evening

Total food to kitten =
`2k+2k=4k`

Food fed to dog = 1 time in morning + 1 time in evening

Therefore, the total amount of food to dog is given as:

Total food to dog = Food in morning + Food in evening

Total food to dog =
`d+d=2d`

Now, the sum of both will give the total amount of food given to both the animals.

Therefore, the expression to represent the total grams of food given to the animals is:

`4k+2d`
