Question

Write the following in decimal notation:

$7\frac{9}{10}$

Answer 1

Step 1

Break the given number into an integer part and a fractional part.

$7\frac{9}{10}=7+\frac{9}{10}$

Step 2

Convert only fractional part into decimal ( divide numerator by denominator). No need to do anything with the integer part.

$\frac{9}{10}=0.9$

Step 3

Add integer part and decimal value of the fractional part.

$7+0.9=7.9$

Hence the decimal notation of $7\frac{9}{10}$ is $7.9$.
