Can a rational number be a irrational number

1 answer:

4 0

Answer:

No. Rational numbers are different from irrational numbers. Rational numbers are numbers that can be written as a fraction. Rational numbers can be a terminating decimal (a number with digits that end/do not repeat) or a repeating decimal (a number with digits that repeat continuously in a pattern). On the other hand, an irrational number is a number that is continuous, and its digits are random.

The heights of a maple tree and a cherry tree have a ratio of 5:2. If the maple tree grew 20 cm and 20 cm was cut off the top of

elena-14-01-66 [18.8K]

Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span> $\frac{x}{y} = \frac{5}{2}$
<span>The new ratio is obtained like this:
</span> $\frac{x+20}{y-20} = \frac{3}{1}$ .
From the above equation we get $x= (y-20)\frac{3}{1} -20$ .
then $\frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}$
Solving the above equation for y we get: $y=160$
So $x=400$
So the first tree is (400-160=240) more taller than cherry tree.
