Question

Number 763.56 can be written as:

• A. 1000 x 7 + 100 x 6 + 10 x 3 + 6
• B. 100 x 7 + 10 x 6 + 1 x 3 + 5 x $\frac{1}{10}$ + 6 x $\frac{1}{100}$
• C. 100 x 7 + 10 x 6 + 1 x 3 + 5 x $\frac{1}{100}$ + 6 x $\frac{1}{10}$
• D. 100 x 7 + 10 x 6 + 1 x 3 + 6 x $\frac{1}{10}$ + 5 x $\frac{1}{100}$

Answer 1

The correct option is B 100 x 7 + 10 x 6 + 1 x 3 + 5 x $\frac{1}{10}$ + 6 x $\frac{1}{100}$

In a decimal number, digits of the whole number part before the decimal point will be at tens, hundreds places etc.
So 763 can be written as 100 x 7 + 10 x 6 + 1 x 3

Also after the decimal point, digits will be at tenths, hundredths places.
So 56 after the decimal point can be written as 5 x $\frac{1}{10}$ + 6 x $\frac{1}{100}$

So 763.56 can be written as :
100 x 7 + 10 x 6 + 1 x 3 + 5 x $\frac{1}{10}$ + 6 x $\frac{1}{100}$
