# Writing and solving proportions powerpoint

RP Analyze proportional relationships and use them to solve real-world and mathematical problems. So x is equal to the cost of 7 markers. Additional teachers must purchase their own license.

Represent proportional relationships by equations. And what I want to do in this video is not solve the word problems but just set up the equation that we could solve to get the answer to the word problems.

The presentation has 37 slides with LOTS of whiteboard practice.

This resource is for one teacher only. Let me do that in the same magenta color. And we could do all of the different scenarios like this. The lesson is in an editable format so you can tailor the lesson to your class.

Or you could flip both sides of this. And then, obviously, you could flip both of these sides. Twice as many examples are provided, compared to a standard textbook.

Let me do x in green. You could say that the ratio of 9 markers to 7 markers is going to be the same as the ratio of their costs, is going to be equal to the ratio of the cost of 9 markers to the cost of 7 markers.

And then you would just have to essentially solve for x. Solving proportions Word problems Video transcript I have three word problems here. So all I would do is flip both sides of this equation right here to get this one over here.

You could call it e for eggs. They are in a pdf form for easy printing. And then you could solve this to figure out how much those 7 markers would cost. How many eggs do we need for a person cake?

I am respond to email quickly. So we have the ratio between the number of apples, 7, and the cost of the apples, 5, is going to be equal to the ratio between another number of apples, which is now x, and the cost of that other number of apples. The ratio of 9 markers to the cost of 9 markers is equal to 7 markers to the cost of 7 markers.

All lessons have a real-world example to aid the students in visualizing a practical application of the concept. Students often get lost in multi-step math problems.

So this is a completely valid proportion here. This will allow for the students to follow the lesson easier. Use proportional relationships to solve multistep ratio and percent problems. Are you looking for the 7th Grade Ratios and Proportions Bundle? This lesson teaches how to write proportions, solve proportions using mental math, and solve real-life problems using proportions to find how many bobble head would people get in a section at a baseball game.

You could also think about the ratios in other ways. You could have A cake recipe for 5 people requires 2 eggs.7th Grade Math Writing Proportions in a PowerPoint Presentation This slideshow lesson is very animated with a flow-through technique.

I developed the lesson for my 7th grade class, Pre-Pre-Algebra, but it can also be used for upper level class reviews.4/5(5). ©b w2L0I1 d24 eK muot wac wSmo9fEt 5wJa8rbe 1 vLFLKCD.
