Three friends are comparing the distance they travelled in a month; Ahmed travelled a distance of km, Hany travelled a distance of km, and John travelled a distance of km. Who travelled the longest distance?
To compare 4-digit numbers, compare the digits in the thousands place. You only need to compare the digits in the hundreds place if the thousands are the same.
Since 4 thousands > 3 thousands > 1 thousand, then km > km > km.
So, Ahmed travelled the longest distance.
