directions are:
write each fraction in simplest form:
(15x^3y^3)/(20x^1y^4)
My answeris: (3x^2)/(4y)
THESE TWO NEXT ONES ARE THE ONES THAT I DON'T UNDERSTAND:
pROBLEM #1
DIRECTIONS: Write each expression in simplest form.
(4x28)/(5x35)
Problem #2
directions:
Write each expression in simplest form.
(4r^225s^2)/(2r^2+3rs20s^2)
Your first answer is correct.
The expression
(4x28)/(5x35)
can be written
(4/5)[(x7)/(x7)]
The (x7) terms cancel out, leaving you with 4/5.
In the lsst expression, factor the numerator and deominator. The numerator is (2r  5s)(2r + 5s)
The denominator factors into
(2r  5s)(r + 4s)
Cancel out the common factors.
when solving x^2=16, why is the answer +/4

1/7 1/3
