Naona ujinga haukutoki, wacha nikuelimishe kidogo bongolala. Wakisema round off wanamaanisha keep it simpler by presenting it as the nearest significant number referenced. In this case, rounding off to the nearest hour he significant number reference is a full hour. Kwa hivo utaangalia hiyo figure iko kati ya which two full hours. Figure inayoongelewa ni 3:35, yani masaa matatu na dakika thelathini na tano. Hiyo figure iko katikati ya 3hrs na 4hrs lakini iko karibu na 4 hours zaidi (dakika 25) kuliko 3 hrs (dakika 35). Kwa hivo ukiround off 3:35 to the nearest hour unapata 4 hours. Nyie watu somo la hisibati liliwapita sana.Nimeone humu mkikosea vitu rahisi tilivyofunzwa shule ya msingi na mnajiita graduates. Masomo yenu duni sana.
