Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.

So, the first solution is a calculator but sometime we don't have a calculator so, do

200 X 300 = A

40 X 90 = B

9 X 8 = C

then add just do multiplication from there like

A + B = D

D + C = E

Then your finally answer would be E

Hope that helps that's the way I do math quick in my head

(Btw the answer to 249 X 398 = 63,672 )

answer: 4/6 =5/7.5

step-by-step explanation: it is based on scale and the scale between the two is 1.25. the answer is correct but i dont know if i explained it right
