Trosi unedau mwy yn unedau llai
I drosi uned fwy鈥檔 uned lai (ee \({m}\) i \({cm}\)) dylet ti wirio yn gyntaf sawl uned lai sydd ei hangen i wneud \({1}\) uned fwy. Wedyn, lluosa鈥檙 rhif hwnnw 芒 nifer yr unedau mwy.
Trosi unedau llai yn unedau mwy
I drosi uned lai鈥檔 uned fwy (ee \({cm}\) i \({m}\)), dylet ti ei rhannu 芒 nifer yr unedau llai sydd eu hangen i wneud \({1}\) uned fwy.
Enghraifft
\({1}~{m} = {100}~{cm}\)
Felly, i drosi o \({m}\) i \({cm}\) lluosa 芒 \({100}\), ac i drosi o \({cm}\) i \({m}\) rhanna 芒 \({100.}\)
Er enghraifft:
\({3.2}~{m} = {320}~{cm}\) (\({3.2}\times{100} = {320}\))
\({400}~{cm} = {4}~{m}\) (\({400}\times{100} = {4}\))
Question
Trosa鈥檙 canlynol i鈥檙 unedau sydd mewn cromfachau:
a) \({5,120}~{g}\) (\({kg}\))
b) \({15}~{cl}\) (\({ml}\))
c) \({245}~{mm}\) (\({m}\))
a) \({5.12}~{kg}\). Cofia fod \({1}~{kg} = {1,000}~{g}\). I drosi o \({g}\) i \({kg}\), rhanna 芒 \({1,000}\).
b) \({150}~{ml}\). Cofia fod \({1}~{cl} = {10}~{ml}\). I drosi o \({cl}\) i \({ml}\), lluosa 芒 \({10}\).
c) \({0.245}~{m}\). Cofia fod \({1}~{m} = {1,000}~{mm}\). I drosi o \({mm}\) i \({m}\), rhanna 芒 \({1,000}\).
