1. Rabin lita na madarar sabo da aka haɗa da miyar pudding, sannan nawa ne adadin madarar da za a saka a cikin miyar pudding?
A. 5000 ml
B. 500 cc
C. 50 dm 3
D. 5 m 3
An sani:
Ƙarar madara = lita 0.5
Ana so : lita 0.5 = ….. ml = ….. cm 3 (cc) = ….. dm 3 = ….. m 3
Magani:
Lita 1 = millilita 1000 (ml 1000)
Lita 1 = 0.001 m 3 = 1 dm 3 = 1000 cm 3 (1000 cc)
Lita 0.5 = (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
Amsar da ta dace ita ce B.
2. Idan aka ƙara ruwa 250 cc a cikin millilita 100 na madarar ruwa, to adadin gaurayawan da aka samar kenan.
A. 12.5 dm3
B. 1.25 dm 3
C. 3.5 dm 3
D. 0.35 dm 3
An sani:
Ƙarar madara = 100 ml
Yawan ruwa = 250 cc = 250 cm 3
Ana so : 100 ml + 250 cc = ….. dm 3
Magani:
ml = millilita
cc = cm 3 = santimita mai siffar sukari
dm 3 = mita mai siffar cubic deci
1 dm 3 = lita 1 = millilita 1000 don haka millilita 100 = lita 100/1000 = lita 1/10 = lita 0.1 = 0.1 dm 3
1 dm 3 = 1000 cm 3 don haka 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
Amsar da ta dace ita ce D.
3. Aji wanda tsawonsa mita 10 ne kuma faɗinsa mita 8 ne, ana amfani da yumbu a matsayin bene . Girman yumbu shine 20 cm x 20 cm. Adadin yumbu a ƙasan ɗakin shine….
A. 20
B. 200
C. 2000
D. 20000
An sani:
Girman ɗaki:
Tsawon = mita 10
Faɗi = mita 8
Faɗin ɗaki = 10 mx 8 m = 80 m2
Girman yumbu:
Tsawon = 20 cm
Faɗi = 20 cm
Yankin yumbu = 20 cm x 20 cm = 400 cm 2
Ana so: Adadin yumbu da ake amfani da shi a matsayin bene
Magani:
1 mita = 100 cm
1 m 2 = 10,000 cm 2
Don haka 80 m 2 = 80 x 10,000 cm 2 = 800,000 cm 2
Adadin yumbu = yankin ɗaki / yanki na yumbu
Adadin yumbu = 800,000 cm 2 / 400 cm 2
Adadin yumbu = 2000

4. Kowace daƙiƙa, kimanin lita 4 na ruwa yana digawa daga akwatin kifaye zuwa cikin akwati mai lita 5. Akwatin ya cika sosai a cikin daƙiƙa ……..
A. Daƙiƙa 125
B. Daƙiƙa 200
C. Daƙiƙa 1250
D. Daƙiƙa 2000
An sani:
Lita 1 = 1 dm 3 = 1000 cm 3
Yawan ruwa = 4 cc = 4 cm 3
Girman akwati = lita 5 = 5 dm 3 = 5 x 1000 cm 3 = 5000 cm 3
Ana so: Tazarar lokaci an cika kwandon da ruwa
Magani:
5000 cm 3/4 cm 3 = daƙiƙa 1250
Madaidaicin amsar ita ce C.
5. Uwa ta sayi ruwan sha galan 2 (galan 1 = lita 19) tare da farashi $2 . Idan girman kofi ɗaya na ruwa ya kai 200 ml, to a tantance farashin kofi ɗaya na ruwa.
An sani:
galan 1 = lita 19
Galan 2 = Lita 2 x 19 = Lita 38
Lita 1 = millilita 1000
Lita 38 = millilita 38 x millilita 1000 = millilita 38,000
Gilashin ruwa 1 = millilita 200
Ana nema: Farashin kofi ɗaya na ruwa
Magani:
Galan 2 na ruwa = lita 38 = millilita 38,000
Kofi 1 na ruwa = millilita 200
38,000 ml / 200 ml = 190
A cikin galan biyu na ruwa akwai kofuna 190 na ruwa.
Farashin galan biyu na ruwa = $2
Farashin kofi 1 na ruwa = $2 / 190 = $0.01
1. Matsala: Juya kilomita 50 zuwa mil. (mil 1 ≈ 1.60934 km)
Maganin: 50 km × (mil 1/1.60934 km) = mil 31.07.
2. Matsala: Kana da lita 2 na ruwa. Millilita nawa ne wannan? (Lita 1 = millilita 1,000)
Maganin: Lita 2 × 1,000 ml/lita = 2,000 ml.
3. Matsala: Jariri yana da nauyin fam 8 da oza 5. A mayar da shi zuwa gram. (fam 1 = gram 453.59237 da oza 1 = gram 28.3495)
Maganin: Fam 8 × 453.59237 g/fam + oza 5 × 28.3495 g/oza = gram 3,628.73896 + gram 141.7475 = gram 3,770.48646.
4. Matsala: Tanki yana ɗauke da galan 100 na ruwa. Maida shi zuwa lita. (galan 1 ≈ lita 3.78541)
Maganin: galan 100 × lita 3.78541/galan = lita 378.541.
5. Matsala: Canza santimita 250 zuwa mita. (100 santimita = mita 1)
Maganin: 250 cm ÷ 100 cm/mita = mita 2.5.
6. Matsala: Mota tana tafiya da gudun mil 55 a kowace awa. Maida wannan gudun zuwa ƙafa a kowace daƙiƙa. (mil 1 = ƙafa 5,280 da awa 1 = daƙiƙa 3,600)
Magani: Mil 55 × ƙafa 5,280/mil ÷ daƙiƙa 3,600 = ƙafa 81.78/daƙiƙa.
7. Matsala: Girke-girke yana buƙatar gram 200 na sukari. A mayar da shi zuwa oza. (oza 1 ≈ gram 28.3495)
Maganin: gram 200 × (ounce 1/gram 28.3495) = oza 7.055.
8. Matsala: Ɗaki yana da faɗin murabba'in ƙafa 300. Maida shi zuwa murabba'in ƙafa 1 ≈ murabba'in mita 0.092903)
Maganin: ƙafa 300 murabba'i × 0.092903 murabba'i mita/ƙafa 27.8709 murabba'i.
9. Matsala: Kana da igiya mai tsawon inci 150. Maida wannan zuwa yadi. (yadi 1 = inci 36)
Magani: Inci 150 ÷ Inci 36/yadi = yadi 4.1667.
10. Matsala: Kwalba tana ɗauke da mai millilita 500. A mayar da ita zuwa kwata. (kwata 1 ≈ 946.353 millilita)
Maganin: millilita 500 × (kwata 1/millilita 946.353) = lita 0.5283.
