What is the fewest number of 7's that can be added together to make their sum greater than 4000?

A. 4001
B. 572
C. 571
D. 470

4000/7 = 571.4

so we need a little more than 571
572 will do
572 * 7 = 4004, check :)

4,000 / 7 = ?

thanks both of you!

You're welcome.

To find the fewest number of 7's that can be added together to make their sum greater than 4000, we can start by dividing 4000 by 7 to determine how many complete sets of 7 we can add together without exceeding 4000.

4000 ÷ 7 = 571.42857...

Since we cannot add a fraction of a 7, we will use the largest whole number that we got from the division, which is 571. This means that we can add 571 sets of 7 together to get a sum of 3997.

To exceed 4000, we need to add at least one additional 7. Therefore, the fewest number of 7's that can be added together to make their sum greater than 4000 is 572.

Therefore, the answer is B. 572.
