Answer 2

Answer:

1100

Step-by-step explanation:

the actual value is 1084

to round off to the nearest tens we round off only the ones digit i.e 4

to round of to the nearest hundreds we must round off the ones and the tens digits i.e 4 and 8 respectively

you dont have to memorise  these rules just think logically

nearest tens deals with a change in the tens place for which you have to round off the ones dig

nearest hundreds deals with a change in the hundreds place so you have to round off the ones and tens place digits.

now lets move on to the number

770+314=1084

we must 1st round off ones digit 4

then round off next digit

while rounding off ;

if the number or digit is less than 5, simply put zero in its place

if the number or dig is greater than 5 then add one to the next dig, which is the tens dig in this case

now if the number or digit is equal to 5, then take a look at the next dig, if that dig is even then round of the first dig as zero and move on... if the dig is odd, add one to it and move on after making the first dig zero.

but in primary school we generally take 5 as belonging to the greater half so we just add 1 to the next dig and dont mind whether it is even or odd

when you reach secondary, you will learn about the case of 5...

so now,

1084

4<5 so put 0

number is now 1080

now tens place number is 8

8>5 so add one to hundreds place dig

so number is 1100

hope it helps.........
