In YIS, next week, April 28-May 1 is going to be a big exam week. For math, the exam is going to be about ratios and Algebra.

The two ideas I know about Ratios is:

- Always multiply, divide the numbers by the same value. {E.g.
**3:2 (all times by 2)**=**6:4**} - Ratio compares different values, it’s used in a lot things instead of another symbol that you won’t very notice. {E.g. The rate,
**6liters/hour**, in ratio is**6liters:1 hour**}

The two ideas I know about Algebra is:

- Mostly everything you find in math, all has something to do with algebra. {E.g. Solving the angles of a shape.}
- If there is an equal sign in a problem, it means it’s a equation. If there is no equal sign in a problem, it means that you have to finding like terms. {Eg.
**4x-1+5x+2——->this is a equation**}*5x+4y+7+8+9+6u+5y————->this is finding like terms*

**QUESTIONS on ALGEBRA and RATIO!!**

- 9:3 —–> ?:21
- What’s 7kg/hour in ratio?
- What’s the angle of the following?
- Find the “x” angle in the following shape.

**Which topic did you find more interesting?**

I found algebra more interesting because algebra is very useful that it’s used in a lot of math topics like finding the angle of a shape, finding the area of a shape etc. Also, algebra has a lot of different kinds of expression so it was interesting.

**Which topic or concept did you find most challenging?**

I found ratio more challenging because sometimes its hard for me to understand the ratio word problems and when other people show me how to do it, I can’t even understand it. If I use algebra to solve ratio word problems, it will be much more easier for me.

**What can you do to improve your knowledge of your two topics?**

I can review sometimes(rote repetition) so I can always remember the concept and I can always remember how to do ratio and algebra questions.
