• B. 36.586
• C. 36.584
• D. 38.87

Answer 1

The correct option is A

38.89

We need to find the value of $\frac{256}{100}+\frac{357}{10}+\frac{63}{100}.$
We first comvert the fractions into decimals.

Dividing by 10 moves the decimal point one place to the left and dividing by 100 moves the point two places to the right.

$\frac{256}{100}=2.56\frac{357}{10}=35.7\frac{63}{100}=0.63$

$\frac{256}{100}+\frac{357}{10}+\frac{63}{100}=2.56+35.7+0.63$

$\therefore \begin{array}{c}1\\ 2.56\\ 35.70\\ +\underset{–}{0.63}\\ \underset{–}{38.89}\end{array}$
