Question

Round 18.57631 to three decimal places.

Answer 1

❄ Hi there,

let us revise the rounding rules and then, get down to rounding the number.

$\sf{Rounding \ Rules:}$

• If the number you need to round is followed by a number from 0 to 4, you round down.
• If the number you need to round is followed by a number that's 5 or more, you round up.

Now we can start the rounding process.

Reading the problem & the directions, we notice that we need to round to 3 decimal places (3 numbers after the decimal point).

Looking at the fourth number, we notice that it's less than 5.

∴ we need to round down ↡

↬$\sf{18.57631 \ rounded \ to \ 3 \ DP \ = \bf{18.576}}$
