Question

Write the number of decimal places in 7.00349.

Answer 1

Hint:The question is related to the number system. The number is in the form of decimal, by considering the decimal place value chart we write the number in place value chart. Note down how many numbers are present after and before the decimal point.

Complete step by step answer:
The numbers can be expressed in many forms. Usually we represent a number in fraction form, decimal form, scientific form and exponential form. Here the given number is in the form of decimal, where the number contains a decimal point.

In Algebra, decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point. The place value system for the decimal number is generally represented as

Ones$1$	Decimal point	Tenths\[\dfrac{1}{{10}}\]	Hundredths\[\dfrac{1}{{100}}\]	Thousandths\[\dfrac{1}{{1000}}\]	Ten Thousandths\[\dfrac{1}{{10000}}\]	Millionths\[\dfrac{1}{{100000}}\]
7	.	0	0	3	4	9

The given number is written in the decimal place value chart. There is one number before the decimal point and after the decimal point there are 5 numbers and they are 0, 0, 3, 4 and 9. The number of decimal places in 7.00349, this statement tells how many numbers are present after the decimal point.

Therefore the number of decimal places in 7.00349 is 5.

Note: Understanding or analysing the question is a very important thing. How many numbers are there in the decimal place values, this information we have in the given question. The decimal place value system chart will give the clear picture of the decimal number.
