Q.1 Write in decimal form :700+20+9/100​

Answer 1

Decimal form => 720.09

Given:

700+20+9/100​

To Find:

The decimal form of the given exponent form

Solution:

• The given question is in exponential form. we need to change it to decimal form.

• The place value of a digit always depends upon the place or position of a digit in that numeral.

=> 700+20

7 is in the hundreds place => 7 x 100 = 700

2 is in the tens place => 2 x 10 = 20.

Keep 0 in ones place as there is no number.

• The first digit after the decimal point always represents tenths place, then hundredths place, thousandths place, and so on.

Keep 0 in tenths place as there is no number.

=> 9/100​

=> 0.09

Exponential form => $700+20+0+0+\frac{9}{100}$

Decimal form => 720.09
