Molly had 125 pickles to put into jars for her mothers market. Her dad gives her 8 jars to use. How many pickles will she not be able to fit evenly into the jars?
125 Γ· 8 = 15 remainder 5
Therefore, 5 of the pickles cannot fit into the jars evenly. There will be 15 pickles in each jar.

What is the dividend if the divisor is 3 and the quotient is 845?
*hint* know your vocabulary
Dividend Γ· Divisor = Quotient
___ Γ· 3 = 845
I can use inverse operation to solve.
3 x 845 is 2,535 and then check using division.
Marianela bought 33 packages of pink erasers and 25 packages of glow-in-the-dark erasers for the school store. Packages of pink erasers cost $12 each and packages of glow-in-the-dark erasers cost $19 each. Marianela says she spent about $850, is her answer reasonable? Explain.
a. Yes, because (30 Γ $10) + (25 Γ $20) = $800.
b. Yes, because (30 Γ 25) + ($10 Γ $20) = $950.
c. No, because (30 Γ 30) + ($10 Γ $20) = $1,100. d. No, because (30 + 30) Γ ($10 Γ $20) = $1,200.
A. 33 rounds to 30 and 12 rounds to 10, 19 rounds to 20.
And when multiplied and combined those equal 800
