Question

give a rough estimate by rounding off to nearest hindred and also closer estimate by tounding off to nearest tens : 468 +243+5416​

Answer 1

Answer:

6100 and 6130.

Step-by-step explanation:

468+243+5416 = 6127

Nearest hundred to 6127 is 6100.

Nearest tens to 6127 is 6130.

Concept :-

while rounding to nearest hundred, first check last two digits (tens and ones digits). Let say xy.

If xy < 50, just make the last two digits zeros.

If xy >= 50, add 100 to the number and then make the last two digits zeroes.

Similarly while rounding to nearest ten, first check units digit of the number. Let say z.

If z < 5, just make the units digit zero.

if z >= 5, add 10 to the number and then make the units digit zero.
