Wow look! The candy store, mom! There's a sale, $9.99 for 5 pounds of any candy. Can we get some?
Sure! But let's make sure that the candy you want isn't all the heavy weighted stuff so you don't go over the 5 pound's.
$9.99 x.275 -------- 4995 69930 199800 -------- 274725 then 2.74725 and round to $2.75
What do you mean? How can we figure that out?
We will weight it and we get to use 3x3 multiplication! I'll teach you.
Pick out the candies you want and be sure to get some of those good looking pop rocks!
We are a bit over 5 pounds. Let's see how much over using 3x3 multiplication.
So the first step is to multiply the entire row (9.99) by 5 because that is the first number on the bottom right. Then the same row by 7. Then lastly the row by 2. Finally, count your decimals. There are 5 so but you decimal in front of the fifth number then round.
Thanks for the candy mom, and the math lesson too!
The total is $9.99 + 2.75, so it's $12.74
