Question

The population, P, of a small island was 6380, correct to the nearest 10. Complete the statement about the limits of P. ………………………………. ≤ P < ……………………………

Answer 1

6375 ≤ P < 6385

Explanation:

When rounding to the nearest 10, the unit value is either rounded to 1 and added to the tens value (if value is greater than or equal to 5) or rounded to 0 (if less Than 5)

Hence, the lower limit of a number p which gives 6380 when rounded to the nearest ten would be 6375 ;

The upper limit of the number p in other to give 6380 when rounded to the nearest 10 will be 6384 (< 6385)
