Question

Estimate your answer for 7.13x6. Explain your reasoning using words,pictures or numbers.

Answer 1

Answer:

$7.13\times 6 =42.78$      

Step-by-step explanation:

We have to evaluate the following expression:

$7.13\times 6$

This could be done with the help of distributive property of multiplication over addition.

Distributive property help us to evaluate complicated multiplication problem easily.

$a\times b = a\times (c+d) = (a\times c) + (a\times d)$

We can evaluate the given function as follows:

$7.13\times 6\\= (7 + 0.13)\times 6\\=(7\times 6) + (0.13\times 6)\\= 42 + 0.78\\=42.78$

Answer 2

You would round 7.13 to 7 then multiply it by 6 which gives you 42
