Answer 2

Solution :-

(2)

→ Total capacity of thermos flask = 2.5L

So,

→ Chocolate needs = 2.5/2 = 1.25L

now,

→ 1L = 1000mL

→ 1.25L = 1000 * 1.25 = 1250 mL (Ans.)

(3)

→ Total capacity of thermos = (1/2) gallon

and,

→ Each day she fills = 1 pint = (1/8) gallon

then,

→ Total number of times = (1/2) ÷ (1/8) = (1/2) * 8 = 4 times (Ans.)
