1. Hafu yerita yemukaka mutsva wakasanganiswa nemuto wepudding, saka mukaka unofanira kuiswa mumuto wepudding unenge wakaita sei…

A. 5000 ml

B. 500 cc

C. 50 dm ³

D. 5 m ³

Zvinozivikanwa:

Huwandu hwemukaka = 0.5 litres

Zvinodiwa : 0.5 litre = ….. ml = ….. cm ³ (cc) = ….. dm ³ = ….. m ³

Solution:

1 litre = 1000 milliliters (1000 ml)

1 litre = 0.001 m ³ = 1 dm ³ = 1000 cm ³ (1000 cc)

0.5 litre = (0.5)(1000 ml) = 500 ml

0.5 dm ³ = (0.5)(1000 cc) = 500 cc

0.5 litre = 0.5 dm ³ = 0.0005 ^m3

Mhinduro chaiyo ndeiyi B.

2. Kana mukaka wemvura wakawedzerwa 250 cc yemvura mu100 milliliters, saka musanganiswa mingani unogadzirwa.

A. 12.5 ^dm3

B. 1.25 dm ³

C. 3.5 dm ³

D. 0.35 dm ³

Zvinozivikanwa:

Huwandu hwemukaka = 100 ml

Huwandu hwemvura = 250 cc = 250 cm ³

Zvinodiwa : 100 ml + 250 cc = ….. dm ³

Solution:

ml = mililita

cc = cm ³ = cubic centimeter

dm ³ = mita ye cubic deci

1 dm ³ = 1 litre = 1000 milliliters kuitira kuti 100 milliliters = 100/1000 litres = 1/10 litres = 0.1 litre = 0.1 dm ³

1 dm ³ = 1000 cm ³ kuitira kuti 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

3. Kirasi ine hurefu hwemamita gumi uye upamhi hwayo hunosvika 8 m, ichishandisa ceramic sepasi rayo . Saizi yeceramic i20 cm x 20 cm. Huwandu hweceramics pasi mukamuri ndi….

A. 20

B. 200

C. 2000

D. 20000

Zvinozivikanwa:

Kukura kwekamuri:

Kureba = mamita gumi

Upamhi = mamita masere

Nzvimbo yekamuri = 10 mx 8 m = 80 ^m2

Saizi yeceramic:

Kureba = 20 cm

Upamhi = 20 cm

Nzvimbo yeceramic = 20 cm x 20 cm = 400 cm ²

Zvinodiwa: Huwandu hwezviumbwa zvesimbi zvinoshandiswa pasi

Solution:

1 m = 100 cm

1 m ² = 10,000 cm ²

Saka 80 m ² = 80 x 10,000 cm ² = 800,000 cm ²

Nhamba yeceramics = nzvimbo yekamuri / nzvimbo yeceramic

Nhamba yezvombo zvesimbi = 800,000 cm ² / 400 cm ²

Nhamba yezvombo zvesimbi = 2000

4. Sekondi yega yega mvura inosvika 4 cc yaidonhedzwa kubva mu aquarium ichipinda mumudziyo we 5 litre . Mudziyo wacho unozadzwa zvizere mukati memasekonzi ……..

A. Masekondi zana nemakumi maviri nemashanu

B. Masekondi mazana maviri

C. Masekondi maviri

D. Masekondi mana

Zvinozivikanwa:

1 litre = 1 dm ³ = 1000 cm ³

Huwandu hwemvura = 4 cc = 4 cm ³

Vhoriyamu yemudziyo = marita mashanu = 5 dm ³ = 5 x 1000 cm ³ = 5000 cm ³

Zvinodiwa: Nguva iyo mudziyo unozadzwa nemvura

Solution:

5000 cm ³ / 4 cm ³ = 1250 masekondi

Mhinduro chaiyo ndeinoti C.

5. Amai vakatenga mvura yekunwa magaroni maviri (garoni rimwe = marita gumi nemapfumbamwe) nemutengo wa $2 . Kana huwandu hwekapu yemvura huri 200 ml, saka sarudza mutengo wekapu yemvura.

Zvinozivikanwa:

1 galoni = 19 marita

Magaroni maviri = 2 x 19 marita = 38 marita

1 litre = 1000 milliliters

Marita makumi matatu nemasere = 38 x 1000 milliliters = 38,000 milliliters

Girazi rimwe remvura = 200 milliliters

Zviri Kudiwa: Mutengo wekapu yemvura

Solution:

Magaroni maviri emvura = marita makumi matatu nemasere = 38,000 milliliters

Kapu imwe yemvura = 200 milliliters

38,000 ml / 200 ml = 190

Mumagaroni maviri emvura mune makapu zana nemakumi mapfumbamwe emvura.

Mutengo wemarita maviri emvura = $2

Mutengo wekapu imwe yemvura = $2 / 190 = $0.01
