1. Ọkara lita mmiri ara ehi ọhụrụ agwakọtara ya na ihendori pudding, kedu ka mmiri ara ehi a ga-etinye n'ime ihendori pudding?
A. 5000 ml
B. 500 cc
C. 50 dm 3
D. 5 m 3
A maara:
Olu mmiri ara ehi = lita 0.5
Achọrọ : lita 0.5 = ….. ml = ….. cm 3 (cc) = ….. dm 3 = ….. m 3
Ngwọta:
1 lita = 1000 mililita (1000 ml)
1 lita = 0.001 m 3 = 1 dm 3 = 1000 cm 3 (1000 cc)
0.5 lita = (0.5)(1000 ml) = 500 ml
0.5 dm 3 = (0.5)(1000 cc) = 500 cc
Lita 0.5 = 0.5 dm 3 = 0.0005 m 3
Azịza ya ziri ezi bụ B.
2. Ọ bụrụ na etinyere 250 cc mmiri n'ime 100 mililita mmiri ara ehi, mgbe ahụ ole ngwakọta a na-emepụta.
A. 12.5 dm3
B. 1.25 dm 3
C. 3.5 dm 3
D. 0.35 dm 3
A maara:
Olu mmiri ara ehi = 100 ml
Olu mmiri = 250 cc = 250 cm 3
Achọrọ : 100 ml + 250 cc = ….. dm 3
Ngwọta:
ml = milliliter
cc = cm 3 = cubic centimita
dm 3 = cubic deci mita
1 dm 3 = 1 lita = 1000 milliliters nke mere na 100 milliliters = 100/1000 lita = 1/10 lita = 0.1 lita = 0.1 dm 3
1 dm 3 = 1000 cm 3 nke mere na 250 cm 3 = 250/1000 dm 3 = 1/4 dm 3 = 0.25 dm 3
100 ml + 250 cm 3 = 0.1 dm 3 + 0.25 dm 3 = 0.35 dm 3
Azịza ya ziri ezi bụ D.
3. Klas nke ogologo ya dị mita iri na obosara ya dịkwa mita asatọ, nke e ji seramiiki mee ala ya . Nha seramiiki ahụ bụ 20 cm x 20 cm. Ọnụọgụ seramiiki dị n'ala ụlọ ahụ bụ….
A. 20
B. 200
C. 2000
D. 20000
A maara:
Nha ụlọ:
Ogologo = mita iri
Obosara = mita 8
Mpaghara ụlọ = 10 mx 8 m = 80 m2
Nha nke seramiiki:
Ogologo = 20 cm
Obosara = 20 cm
Mpaghara seramiiki = 20 cm x 20 cm = 400 cm 2
Achọtara: Ọnụọgụ seramiiki e ji mee ala
Ngwọta:
1m=100cm
1 m 2 = 10,000 cm 2
Ya mere, 80 m 2 = 80 x 10,000 cm 2 = 800,000 cm 2
Ọnụọgụ seramiiki = mpaghara ụlọ / mpaghara seramiiki
Ọnụọgụ seramiiki = 800,000 cm 2 / 400 cm 2
Ọnụọgụ seramiiki = 2000
Azịza ya ziri ezi bụ C.
4. Kwa sekọnd, ihe ruru 4 cc mmiri na-esi na akwarium apụta n'ime akpa lita 5. A na-ejupụta akpa ahụ nke ọma n'ime sekọnd ……..
A. Sekọnd 125
B. Sekọnd 200
C. Sekọnd 1250
D. sekọnd 2000
A maara:
1 lita = 1 dm 3 = 1000 cm 3
Olu mmiri = 4 cc = 4 cm 3
Olu nke akpa ahụ = lita 5 = 5 dm 3 = 5 x 1000 cm 3 = 5000 cm 3
Achọrọ: Oge oge a na-ejupụta akpa ahụ na mmiri
Ngwọta:
5000 cm 3/4 cm 3 = sekọnd 1250
Azịza ya ziri ezi bụ C.
5. Nne zụtara mmiri ọṅụṅụ galọn abụọ (galọn otu = lita 19) na ọnụ ahịa $2 . Ọ bụrụ na olu iko mmiri bụ 200 ml, chọpụta ọnụ ahịa iko mmiri.
A maara:
1 galọn = 19 lita
Galọn abụọ = lita abụọ x iri na itoolu = lita iri atọ na asatọ
1 lita = 1000 mililita
Lita 38 = 38 x 1000 mililita = 38,000 mililita
Otu iko mmiri = 200 mililita
Achọrọ: Ọnụ ahịa otu iko mmiri
Ngwọta:
Galọn mmiri abụọ = lita 38 = millilita 38,000
1 iko mmiri = 200 mililita
38,000 ml / 200 ml = 190
N'ime galọn mmiri abụọ, e nwere iko mmiri 190.
Ọnụ ahịa galọn mmiri abụọ = $2
Ọnụ ahịa otu iko mmiri = $2 / 190 = $0.01
1. Nsogbu: Tụgharịa kilomita 50 gaa na maịlụ. (1 maịlụ ≈ 1.60934 km)
Ngwọta: 50 km × (1 maịlụ/1.60934 km) = 31.07 maịlụ.
2. Nsogbu: I nwere lita mmiri abụọ. Mililita ole ka nke ahụ bụ? (Lita 1 = 1,000 millilita)
Ngwọta: lita 2 × 1,000 ml/lita = 2,000 ml.
3. Nsogbu: Nwa ọhụrụ dị kilogram asatọ na ounces ise. Gbanwee nke a ka ọ bụrụ gram. (1 paụnd = gram 453.59237 na gram 1 ounce = gram 28.3495)
Ngwọta: Paụnd 8 × 453.59237 g/paụnd + ounce 5 × 28.3495 g/ounce = gram 3,628.73896 + gram 141.7475 = gram 3,770.48646.
4. Nsogbu: Tankị na-ebu galọn mmiri 100. Gbanwee nke a ka ọ bụrụ lita. (galọn 1 ≈ lita 3.78541)
Ngwọta: galọn 100 × 3.78541 lita/galọn = lita 378.541.
5. Nsogbu: Gbanwee sentimita 250 ka ọ bụrụ mita. (100 sentimita = mita 1)
Ngwọta: 250 cm ÷ 100 cm/mita = mita 2.5.
6. Nsogbu: Ụgbọala na-aga n'ọsọ nke maịlụ 55 kwa elekere. Gbanwee ọsọ a ka ọ bụrụ ụkwụ kwa sekọnd. (maịlụ 1 = ụkwụ 5,280 na awa 1 = sekọnd 3,600)
Ngwọta: Maịlụ 55 × ụkwụ 5,280/maịlụ ÷ sekọnd 3,600 = ụkwụ 81.78/sekọnd.
7. Nsogbu: Ntụziaka chọrọ gram 200 nke shuga. Gbanwee nke a ka ọ bụrụ ounce. (1 ounce ≈ gram 28.3495)
Ngwọta: gram 200 × (1 ounce/gram 28.3495) = ounce 7.055.
8. Nsogbu: Ụlọ nwere obosara nke sụkwịa 300. Gbanwee nke a ka ọ bụrụ sụkwịa meter. (1 sụkwịa ft ≈ 0.092903 sụkwịa meter)
Ngwọta: sụkwịa 300 × 0.092903 sụkwịa mịta/sụkwịa mịta = sụkwịa mịta mịta 27.8709.
9. Nsogbu: Ị nwere eriri nke dị sentimita 150 n'ogologo. Gbanwee nke a ka ọ bụrụ yaadị. (otu yaadị = sentimita 36)
Ngwọta: sentimita 150 ÷ sentimita 36/yaadị = yaadị 4.1667.
10. Nsogbu: Karama nwere mililita 500 nke mmanụ. Gbanwee nke a ka ọ bụrụ lita. (otu lita ≈ 946.353 mililita)
Ngwọta: mililita 500 × (otu lita/mililita 946.353) = 0.5283 lita.
