Answer 2

Given data: a) $400 + 20 + 5 + \frac{3}{10} + \frac{4}{100}+ \frac{7}{1000}$= ?, b) 6 thousands + 7 hundreds + 2 tenths + 3 thousandths = ?

To find: Decimal form

Solution:

• Decimal form is defined as the number and fraction separated by decimal point and it is also known as special form.
• Considering the first data we have $400 + 20 + 5 + \frac{3}{10} + \frac{4}{100}+ \frac{7}{1000}$. Adding the whole number we get $425+ \frac{3}{10} + \frac{4}{100}+ \frac{7}{1000}$.
• Solving the fraction we get $\frac{3}{10} + \frac{4}{100}+ \frac{7}{1000}=.347$. Now combining both whole number and fraction we have 425.347.
• Considering the second data we have 6 thousands + 7 hundreds + 2 tenths + 3 thousandths. Adding the whole number and fraction ( 6 thousands + 7 hundreds = 6700 and 2 tenths + 3 thousandths = .203).
• Hence the decimal forms are a) 425.347 and b) 6700.203.
