Nā pilikia a me nā hoʻonā e pili ana i ka hoʻololi ʻana o nā ʻāpana - nā pilikia a me nā hoʻonā

1. Hapalua lita o ka waiū hou i kāwili ʻia me ka mea ʻono pudding, a laila he aha ka nui o ka waiū e hoʻokomo ʻia i loko o ka mea ʻono pudding…

A. 5000 ml

B. 500 cc

C. 50 dm ³

D. 5 ^m3

ʻIke ʻia:

Ka nui o ka waiū = 0.5 lita

Makemake ʻia : 0.5 lita = ….. ml = ….. kenimika ³ (cc) = ….. dm ³ = ….. m ³

Lōlā:

1 lita = 1000 milliliters (1000 ml)

1 lita = 0.001 m3 ⁼ 1 dm3 ⁼ 1000 kenimika3 ⁽ 1000 cc)

0.5 lita = (0.5)(1000 ml) = 500 ml

0.5 dm ³ = (0.5)(1000 cc) = 500 cc

0.5 lita = 0.5 dm3 ⁼ 0.0005 ^m3

ʻO ka pane pololei ʻo B.

2. Inā i loko o 100 mililita o ka waiū wai i hoʻohui ʻia he 250 cc o ka wai a laila ehia mau hui ʻana i hana ʻia.

A. 12.5 ^dm3

B. 1.25 dm ³

C. 3.5 dm ³

D. 0.35 dm ³

ʻIke ʻia:

Ka nui o ka waiū = 100 ml

Ka nui o ka wai = 250 cc = 250 ^cm3

Makemake ʻia : 100 ml + 250 cc = ….. dm ³

Lōlā:

ml = milliliter

cc = cm ³ = kenimika cubic

dm ³ = mika desi cubic

1 dm ³ = 1 lita = 1000 milliliters i hiki ai i 100 milliliters = 100/1000 lita = 1/10 lita = 0.1 lita = 0.1 dm ³

1 dm ³ = 1000 kenimika ³ i hiki ai i 250 kenimika ³ = 250/1000 dm ³ = 1/4 dm ³ = 0.25 dm ³

100 ml + 250 kenimika ³ = 0.1 dm ³ + 0.25 dm ³ = 0.35 dm ³

ʻO D ka pane pololei.

3. He lumi papa nona ka lōʻihi he 10 m a ʻo kona laulā he 8 m, e hoʻohana ana i ka keramika ma ke ʻano he papahele . ʻO ka nui o ka keramika he 20 cm x 20 cm. ʻO ka nui o nā keramika ma ka papahele o ka lumi….

H. 20

B. 200

C. 2000

D. 20000

ʻIke ʻia:

Ka nui o kahi lumi:

Loa = 10 mika

Ka laulā = 8 mika

ʻĀpana o kahi lumi = 10 mx 8 m = 80 ^m2

Ka nui o ka keramika:

Loa = 20 kenimika

Ka laulā = 20 kenimika

ʻO ka nui o ka keramika = 20 kenimika x 20 kenimika = 400 kenimika ²

Makemake ʻia: ʻO ka nui o nā keramika i hoʻohana ʻia ma ke ʻano he papahele

Lōlā:

1 mika = 100 kenimika

1 m² ⁼ 10,000 ^kenimika²

No laila, 80 m² ⁼ 80 x 10,000 kenimika² ⁼ 800,000 ^kenimika²

Helu o nā keramika = ka nui o kahi lumi / ka nui o kahi keramika

Helu o nā keramika = 800,000 kenimika ² / 400 kenimika ²

Helu o nā keramika = 2000

ʻO ka pane pololei ʻo C.

4. I kēlā me kēia kekona, e like me 4 cc o ka wai i kahe mai kahi aquarium i loko o kahi pahu 5 lita . Ua piha ka pahu i ka wā ….. kekona.

A. 125 kekona

B. 200 kekona

C. 1250 kekona

D. 2000 kekona

ʻIke ʻia:

1 lita = 1 dm3 ⁼ 1000 ^cm3

Ka nui o ka wai = 4 cc = 4 ^cm3

Ka nui o ka ipu = 5 lita = 5 dm ³ = 5 x 1000 kenimika ³ = 5000 kenimika ³

Makemake ʻia: Ka manawa i hoʻopiha ʻia ai ka ipu me ka wai

Lōlā:

5000 kenimika ³ / 4 kenimika ³ = 1250 kekona

ʻO ka pane pololei ʻo C.

5. Ua kūʻai ʻo Māmā i ka wai inu he 2 galani (1 galani = 19 lita) me ke kumukūʻai he $2 . Inā he 200 ml ka nui o ke kīʻaha wai , a laila e hoʻoholo i ke kumukūʻai o ke kīʻaha wai.

ʻIke ʻia:

1 galani = 19 lita

2 galani = 2 x 19 lita = 38 lita

1 lita = 1000 milliliters

38 lita = 38 x 1000 milliliters = 38,000 milliliters

1 kīʻaha wai = 200 mililita

Makemake ʻia: Ke kumukūʻai o ke kīʻaha wai

Lōlā:

2 galani wai = 38 lita = 38,000 milliliters

1 kīʻaha wai = 200 mililita

38,000 ml / 200 ml = 190

I loko o 2 galani wai he 190 kīʻaha wai.

ʻO ke kumukūʻai o 2 galani wai = $2

Kumukūʻai o 1 kīʻaha wai = $2 / 190 = $0.01
