Answer 1

Answer:

1)8.2×6.7=54.94

2)54.94÷.46=119.43

we round the ANSWER to 1 significant digit since last digit is 3 which is less than 5 i-e 3<5

3)required ans= 119.4

Answer 2

The answer is   $8.2$ × $6.7$ ÷ $0.46$ $= 119$.

Given:

The given number is $8.2$ × $6.7$ ÷ $0.46$

To find:  

    $8.2$ × $6.7$ ÷ $0.46$ rounded to one significant figure.

Solution:

Multiplying the first two terms we get,

$8.2$ × $6.7$ ÷ $0.46$ $= 54.94$  ÷ $0.46$

                        $= \frac{54.94}{0.46}$

Multiplying the numerator and the denominator by $100$,

                          = $= \frac{54.94}{0.46}$ × $\frac{100}{100}$

                             $= \frac{5494}{46}\\= 119.43$

Rounded to one significant figure we get,

                             $= 119$

Hence  $8.2$ × $6.7$ ÷ $0.46$ $= 119$.
