Question

write the following decimal form and say what kind of decimal expansion each has: 36/100,1/11, 4 and 1/8,3/13,2/11,329/400 . Answer with statement and explation . Justify your answer is correct . Correct will be mark as brain list .​

Answer 1

Answer:

Solution:

i) 36/100

36/100 = 0.36

Thus, 36/100 in decimal format is represented as 0.36.

This is a terminating decimal number.

ii) 1/11

The remainder 1 keeps repeating. So, 1/11 = 0.0909... and it can be written as 1/11 = 0.09

iii) 4 1/8

 4 1/8 can be expressed as 33/8 in terms of improper fraction

Thus, 4 1/8 = 33/8 = 4.125

Thus, 4 1/8 in decimal form is written as 4.125.

iv) 3/13

Thus, 3/13 = 0.23076923...

We see that the set of numbers 230769 after the decimal point keeps repeating. So, this is a non-terminating recurring decimal.

v) 2/11

Thus, 2/11 = 0.1818

Here, we see that the block of numbers 18 keeps repeating. Hence, this is a non-terminating recurring decimal.

vi) 329/400

329/400 = 329 ÷ (4 × 100) = 0.8225

Now, 82.25/100 = 0.8225

Thus, 329/400 in decimal form is written as 0.8225.

This is a terminating decimal number because the
