àï6.3è U. S. Measurements of Capacity.
äè Please convert the following U. S. Measurements of
Capacity.
âêêConvert 22 cups to _____ pt.
#ë 2 cupsêï22 cupsè ┌─¥ë 2 ∙ xè =è 22
#ë ──────è =è ───────è │êëxè =è 22/2
#ê1 pt.êèx pt.ë│êëxè =è 11
#êêêêè │
#ê2 ∙ xè =è 1 ∙ 22è──┘ê 22 cups is 11 pints.
éS The U. S. Measurements of Capacity are ounce, cup, pint,
quart, and gallon.ïThe equivalencies between ç units of capacity
are as follows:
êêè8 ounces (oz.)è =è 1 cup (c)
êêêë 2 c.è =è 1 pint (pt.)
êêêë2 pt.è =è 1 quart (qt.)
êêêë4 qt.è =è 1 gallon (gal.)
in order to convert 22 cups to pints, you should set up a
Proportion involving the equivalence, "2 cupsè=è1 pint."
êêêè 2 cupsêï22 cups
#êêêè ──────è =è ───────
êêêè 1 pintêïx pints
Next, you should drop the units and solve the Proportion.
