"He sends five presents."
Translation:그는 선물 다섯 개를 보냅니다.
From the notes:
The general usage is Noun+Number+Counter+Particle in a sentence. • 사람 한 명이 있어요=There is one person Particles can sometimes be attached to the noun instead of the counter. Usually in writing the number and counter are written separately, with a space, but without a space when using a numeral (두 명 vs 2명). Other word orders are also possible in some circumstances, but less popular: • Number+Noun (한 사람) • Number+Counter+의+Noun (한 명의 사람) • Noun+Number (사람 하나)
"Other word orders are also possible in some circumstances, but less popular" -> I don't know what circumstances that might be though.
Hope I helped a bit...
