Mea helu helu unahi
Inā makemake ʻoe e ʻike i ka lōʻihi ma lalo o ka hoʻololi ʻana i nā unahi like ʻole, e hoʻāʻo i kēia,mea paahana hoololi unahi, kōkua ia iā mākou e helu wikiwiki i ka lōʻihi.
Kōkua kēia helu helu iā mākou e ʻimi i ka helu unahi ma waena o ʻelua mau lōʻihi, e hoʻokomo wale i ʻelua mau lōʻihi, e helu ʻakomi ia i ka helu unahi, kākoʻo i nā ʻāpana lōʻihi like ʻole (mm, cm, m, km, in, ft, yd, mi), a me nā mea like. kiʻi hiʻohiʻona a me ke ʻano, hoʻomaopopo maʻalahi i ke kaʻina hana helu a me ka hopena.
Pehea e hoʻohana ai i ka helu helu unahi
- E hookomo i ka loa o A a me B
- ʻAi ʻia ka helu decimal a i ʻole hakina, laʻa. 6, 12, 4.7, 1/2, 5 3/8
- Inā ʻokoʻa nā ʻāpana lōʻihi, koho i ka ʻāpana kūpono
- E helu 'akomi 'ia ka hopena (helu kumu).
Pehea e ʻike ai i ka mea unahi?
I loko o ʻelua mau kiʻi geometric like, ʻo ka mea unahi ka ratio o ko lākou mau ʻaoʻao pili, e puʻunaue ana i nā lōʻihi like ʻelua o nā ʻaoʻao e hāʻawi i ka ratio, no ka laʻana.
He aha ke kumu unahi ma waena o 4 knm a me 10 knm?
Ua puunaueia ka 4 a me ka 10 e ka 2
Loihi A : 4 ÷ 2 = 2
Loihi B : 10 ÷ 2 = 5
no laila, ʻo ka helu pālākiō mai A a i B he 2:5
Ina ua like ka 12 iniha me 3 iniha, heaha ka huina unahi?
Ua puunaueia ka 12 a me 3 e 3
12 ÷ 3 = 4
3 ÷ 3 = 1
ʻO ka ratio 12:3 i maʻalahi ʻia he 4:1
no laila, he 4:1 ka helu unahi o 12 a 3 iniha
Ina ua like ka 1/4 iniha me 2 kapuai, heaha ka huina unahi?
1⁄4 in = 1 ÷ 4 = 0.25 in
2 ft = 12 × 2 = 24 iniha
1 ÷ 0.25 = 4
24 × 4 = 96
0.25:24 maʻalahi ka 1:96
no laila, he 1:96 ka helu unahi o 1⁄4 iniha a 2 kapuai
