Step-by-step explanation:
one gallon is 128oz.
1445 gallons are how many Oz?
that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"
or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"
it all works with multiplication. it is the ultimate application for multiplication.
that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.
and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.
128 × 1445 = 184,960oz
