Question

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

Answer 1

Answer:

Friendly number: 300 it 2 numbers away from 298

then we multiply 300*6 witch gives us 1,800

we also multiply 3*6 witch gives us 1we subtract 1,800-12=1,788

1,788 is you total

Step-by-step explanation:

Answer 2

So, our friendly number will be 300: it's only two numbers away from 298!

We multiply 300 by 6: it's 1800. (3*6=18, and the 0s we can just add at the end)

now we only need to subtract those two numbers (mupliplied by 6): so we subtract 12.

the result will be 1800-12=1788.
