The answer would be 20.

102.3 can be rounded down to 100 and 4.7 can be rounded up to 5. 100 divides by 5 is 20.

The trick is to find the 2 closest numbers that you can do mental math with.

OK  - convert  the 2 numbers  to  one significant figure:-

102.3  = 100
4.7 = 5

So the estimate is 100/5  = 20 answer

How many times can 2 1/2 be subtracted from 12 1/2
Luba_88 [7]
2 1/2 = 2.5
12 1/2 = 12.5

This means you can calculate how may times it goes in by dividing it and rounding the number down:

12.5 / 2.5 = 5

*5 can not be rounded down so it stays the same

This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
