An array of pennies has 4 rows and 6 columns. Which is NOT a way to divide the group equally? A. sixths B. fifths C. fourths D. thirds

OpenStudy (mathteacher1729):

Columns go up and down Rows go left and right. Hint = remember only one, and you'll forever know the other. :-p So you've got a grid of coins that looks like this: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 The question is asking "When you divide the number of coins by (6, 5, 4, or 3) which leaves a remainder?" Hope this helps. :)

Ok, fifths

OpenStudy (anonymous):

its fifths, it cant be divided by five equally, you'll get a remainder :/

OpenStudy (anonymous):

so... \[6\div4\]

OpenStudy (anonymous):

explain Bdude

OpenStudy (anonymous):

the answer to the question is fifths

OpenStudy (anonymous):

ok, the number of pennies total is 24, divide 24 by 6, 5, 4, then 3, and whichever one leaves a remainder, which is five, gives you the answer. since you get 5, the answer is fifths

OpenStudy (anonymous):

because 5 is the denominator of one fifth

OpenStudy (anonymous):

theres the answer. fifths, hope this helps, bye! :S)
