use compatible numbers to find two estimates for 336 divided by 12

Question

Using compatible numbers to find estimates in division

Answer 1

just dig out yer 1$ kalkulater & tipe in 336/12 & it sae anser=28

As far as me kan see, a number mae "kompatabel" if sumwon sae it be

Answer 2

10 is close to 12 and 340 is close to 336, so dividing 340 by 10 just means removing the zero. This gives an estimate of 34. We can also recognise that 336 is only a bit less than 360, and we know that 12 divides into this 30 times. So we have two numbers 34 and 30 as estimates of the true division which is 28.
