6. A large container of popcorn is 5 times as large as a small container of popcorn. A small container of popcorn contains 10 ounces of popcorn. If Caryn has 4 large containers of popcorn, how many ounces of popcorn does she have?

• 19 Ounces

• 50 ounces

• 150 ounces

• 200 ounces

Answer explanation

This is a two step problem!

Step 1- Multiplicative Comparison.

Large = 5 times as many as a small.

We know that small = 10 ounces.

So large = 5 x 10 which we know = 50.

Step 2- Solve for how many total ounces.

4 containers x 50 ounces = 200 ounces.

Can't remember how to multiply 4 x 50? Multiply 4x5 and add zero on the end to bring back the correct place value.

8. Jordan had 36 pencils, which was four times as many as Michael had. Ben had 5 less pencils than Michael. Which steps should be used to find the number of pencils that Ben had?

• divide 36 by 4 then add 5

• divide 36 by 4 then subtract 5

• multiply 36 by 4 then add 5

• multiply 36 by 4 then subtract 5

Answer explanation

Jordan - 36 = 4 x ?
Ben- Michael - 5
To find the missing factor, you can divide the product by the known factor of 4.

$36\div4\ =\ 9\$ is the same as $4\times?=36$
So we first divide 36 into 4 equal parts to find Michael's amount, and then subtract 5 from Michael to find Ben.
