A newborn eats 8 times a day. At each feeding, he eats 2.5 ounces of formula. How many days would it take to eat 100 ounces

It would take 5 days

Explanation:

1. 2.5 times 8 is 20 ounces

2. 2.5 times 16 is 40 ounces

3. 2.5 times 24 is 60 ounces

4. 2.5 times 32 is 80 ounces

5. 2.5 times 40 is 100 ounces

It will take 5 days to eat 100 ounces.

Explanation:

He eats 8 times a day.

Each time he eats, he eats 2.5 ounces.

This means that he eats 20 ounces a day, since 8 x 2.5 is 20.

We now know that he eats 20 ounces a day.

To figure out many days it would take for him to eat 100 ounces, we set up an equation.

20x = 100

The x represents the number of days that it will take for him to eat 100 ounce, and the 20 represents the number of ounces that he eat a day.

20x = 100

Divide both sides by 20, to make solve for x.

20x = 100

/20 / 20

x = 5

It will take 5 days for the baby to eat 100 ounces.
