Question

Round 765 mm to the nearest 100mm

Answer 1

It is over then 749mm. so 800mm.

If it is less or same as 749mm, It is 700mm.

Answer 2

`\huge \boxed{\mathrm{800 \ mm}}`

Explanation:

765 mm to nearest 100 mm would be to round up 765 to nearest hundred.

765 rounded up to nearest hundred’s place would be 800.

The place after 7 is 6, which is higher or equal to 5, so we add 1 to the hundred’s place followed by zeros.
