Kendall feeds her cat a total of 4/5 cup of food every day. She feeds it 1/2 cup of food in the evening. Solve an equation to find how much food she gives to the cat the rest of the day. Write your answer in fraction form only.
Let x be the amount of food Kendall gives to her cat the rest of the day.
The total amount of food given to the cat every day is 4/5 cup.
So, 1/2 cup (evening) + x = 4/5 cup
To find x, we need to subtract 1/2 from 4/5:
x = 4/5 - 1/2
x = 4/5 - 2/4
x = 4/5 - 5/10
x = 8/10 - 5/10
x = 3/10
Therefore, Kendall gives her cat 3/10 cup of food for the rest of the day.
