Show how to multiply 6 x 298 using friendly numbers and then use properties and mental math.
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
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:
\(6 * 298 = 6 * (200 + 90 + 8)\)
