Question

WILL GIVE BRAINLYEST!!!

Answer 1

31.5 times 10.51 = 331.065

Answer 2

Answer: Using the rules of significant figures is 331.065.

Step-by-step explanation:

Since we have given that

3.15 times 10.51.

First we write 3.15 as $\dfrac{315}{10}$

and

We rewrite 10.51 as $\dfrac{10.51}{100}$

According to question,

we use "multiplication" for times:

$31.5\times 10.51=\dfrac{315}{10}\times \dfrac{1051}{100}=\dfrac{331065}{1000}=331.065$

Hence, using the rules of significant figures is 331.065.
