This week we learn about Racional Expressions, basically is with fractions and we can add, subtract, multiply and divide. I will give examples that each:
Add: You first need to see the number you can divide by it, such as 2, 4, and 6, the minimum common multiplier is 12 because 2×6 = 12, 4×3 = 12, 6×2 = 12, and then you’re just the numerators.
Subtract: You need to do the same thing, but instead of adding you subtract.
Multiply: In multiplication you only have to multiply the numerators by the numerators and denominators by the denominated ones and you can have a chance such as 18 over 8 and multiplied by 2 over 9, you cut the 18 with the 9 by itself and the 2 and 8 by it even, the result would be 2 out of 4.
Divide: You do the same only in the second fraction you reverse the numerators down and the denominators up and then there is a multiplication and so is the same process.
