Question

для кішки купили 3кг сушого корму . за перший тиждень вона зїла 1\6 частину корму ,за другий -4/25 залишку , скількі корму ще залишилося?

Answer 1

1 кг=1000г

3кг=3000г

3000:6*1=500(г)=0,5кг съела в 1-ю неделю

3000-500=2500(г)=2,5 кг остаток

2500:25*4=400(г)=0,4 кг

3000-(500+400)=2100(г) =2,1кг корма осталось.

Answer 2

3кг=3000г

3,0*1/6=0,5кг съела за 1неделю

3,0-0,5=2,5 кг осталось корма

2,5*4/25=0,4 кг съела за 2неделю

0,5+0,4=0,9кг съела за 2недели

3,0-0,9 =2,1кг корма осталось

Ответ 2,1 кг корма осталось

Answer 3

According to Google Translate, the message you sent me is in Ukrainian and it means:

Answer in detail. For a cat they bought 3 kg of dry food. In the first week she ate 1/6 of the food, in the second - 4/25 of the remainder, how much food is left?

This is a math problem that can be solved by using algebra. One possible way to solve it is:

- Let x be the amount of food left after the first week. Then we have:

x = 3 - 1/6 * 3 x = 3 - 1/2 x = 2.5

- Let y be the amount of food left after the second week. Then we have:

y = x - 4/25 * x y = 2.5 - 0.16 * 2.5 y = 2.1

- Therefore, the amount of food left after the second week is 2.1 kg.
