Answer: if a/b =/ c, then a =/ bc.
Step-by-step explanation:
inverse means to negate, so if somethings positive you need to change it to negative
a fraction is a representation of a proportion, like say you have a pizza and cut it in 6 pieces, each piece is 1/6 of the pizza,
.
the total number of available slices in the pizza is 6, you cut it in 6 slices, and a single unit of it or just 1, is 1/6 or one sixth of the pizza.
in short, a rational number is one you can write as a fraction, and an irrational number is one that can't be written as a fraction, a good example of those are π , or e euler's constant or √2.
There are eighty cars in the parking lot and sixty eight are not blue.
That's impossible to say. The radius of a square is meaningless.
6 is easy
7. never divide by a fraction, flip ot upside down and multiply, so multiply by 5 on both sides
8. subtract 3.45 on both sides
9. the answer is just 1
