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

Gary went to the store and bought 89 packs of blueberries and 21 packs of strawberries. Each pack of blueberries has 23 in them and each pack of strawberries has 46 in them. 

Lola says that he will have a total of about 2,800 berries. Is Lola correct?

Yes, Lola is correct.

90 x 20 = 1800 and 20 x 50 = 1000.

Add them together and you get about 2,800 berries.
