Multiplication and division word problems Video transcript Let's now see if we can divide into larger numbers. And just as a starting point, in order to divide into larger numbers, you at least need to know your multiplication tables from the 1-multiplication tables all the way to, at least, the multiplication. So all the way up to 10 times 10, which you know is
Word problems Solving two-step equations Video transcript Marcia has just opened her new computer store. What is the minimum number of computer she needs to sell in a month to make a profit?
So I'll let you think about that for a second. Well, let's think about what we have to figure out. We have to figure out the minimum number of computers she needs to sell. So let's set that to a variable or set a variable to represent that.
So let's let x equal the number of computers she sells. Number of computers sold. Now, let's think about how much net profit she will make in a month.
And that's what we're thinking about. How many computers, the minimum number she needs to sell in order to make a net profit?
So I'll write her profit is going to be how much money she brings in from selling the computers. But we're not done yet. What we care about is making a profit. We want this number right over here to be greater than 0. So let's just think about what number of computers would get us to 0.
And then, maybe she needs to sell a little bit more than that. So let's see what gets her to break even. So break even-- that's 0 profit. Neither positive or negative-- is equal to 27 times-- and I'll do it all in one color now.
Well, we've seen equations like this before. We can add 10, to both sides. Add 10, to both sides, so it's no longer on the right-hand side.
And we are left with 10, And then to solve for x, we just have to divide both sides by Divide both sides by On our right-hand side, we have x.
So let me just write this down.The printable worksheets on this page feature simple division with remainders, as well as long division problems. If you'd like to view the Common Core Standard(s) associated with the long division worksheets below, simply click the common core icon.
After we were pretty solid on long division, I introduced the concept of interpreting remainders. While they had been working with remainders, we really hadn't required them to think critically about what the remainders represented, particularly in word problems. You sit at your desk, ready to put a math quiz, test or activity together.
The questions flow onto the document until you hit a section for word problems. A jolt of creativity would help.
