The non-terminating decimal that can be converted into a rational number is given by:

0.321321321.

<h3>What are rational and irrational numbers?</h3>

Rational numbers are numbers that can be represented by fractions, with examples such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.

Irrational numbers are numbers that cannot be represented by fractions, being non-terminating and non-repeating decimals, such as non-exact square roots, and the most common example of an irrational number is the number pi = 3.1415....

In the context of this problem, we are given four non-terminating decimal numbers, in which the only one with a repeating decimal pattern is:

0.321321321...

In which the pattern is:

321.

Hence the number can be written as the following rational number = fraction:

321/999.

With 999 being due to the fact that the repeating pattern is composed by three digits.

How do I multiply 89 x 38 by using partial products? PLEASE ANSWER FAST

olga_2 [115]

Answer:

The result after partial products of 89 x 38 is 3382

Step-by-step explanation:

We need to solve 89 x 38 using partial products.

In Partial products we divide each term such that 89 can be written as 80 and 9 while 38 can be written as 30 and 8

We will multiply each term with other and then find their sum.

Multiplication is shown in figure attached.

Now adding the results of each cell in the table:
