Question

Show how to multiply 6 x 298 using friendly numbers and then use properties and mental math.

Answer 1

For this case we have the following multiplication:

$6 * 298$

We can rewrite this operation to facilitate the calculation.

We have then:

$6 * 298 = 6 * (200 + 90 + 8)$

From here, we apply the distributive property.

We have then:

$6 * 200 + 6 * 90 + 6 * 8$

Rewriting we have:

$1200 + 540 + 48$

Finally adding all the numbers we have:

$1200 + 540 + 48 = 1788$

Answer:

The value of 6 * 298 is 1788 and the calculations can be provided as follows:

$6 * 298 = 6 * (200 + 90 + 8)$

Answer 2

I personally don't like this common core stuff but I think I can answer
friendly numbers
you can make 298 into the 'friendly number' of 300
300 times 6=1800

the friendly number answer is 1800
mental math tells us that it is 1788
close enough
