Question

Helen puts 50 marbles into 9 jars. First, she puts in the greatest

Answer 1

Answer:

She needs 4 more marbles for the 9th jar.

Step-by-step explanation:

Multiples of 8:

M = {0, 8, 16, 24, 32, 40, 48, 56, ...}

First, she puts in the greatest possible number of marbles into each of the 1st 8 jars.

The total is the greatest multiple of 8 below 50, which is 48.

In each jar:

48/8 = 6

The remaining marbles are then put into the 9th jar.

50 - 48 = 2 in the 9th jar.

How many more marbles does she need for the 9th jar such that every jar has the same number of marbles?​

All others have 6, the 9th has 2.

6 - 2 = 4

She needs 4 more marbles for the 9th jar.
