"No: I'm waiting for you to catch up."

"1,875 square yards," said Felix.

"Yes; and now reduce an acre to square yards."

After figuring a few minutes, Felix announced 4,840 square yards in an acre. "What do you do next?" he said.

"One yard, then, would be what part of an acre?" asked Johnny.

After a moment's hesitation, Felix said, "1/4840 of an acre."

"Then, 1,875 square yards would be how many 4,84Oths of an acre?"

"Why," replied Felix, after a little further consideration, "1875/4840 of an acre."

"Now let's reduce that fraction as low as we can, by dividing both terms by five, and what does it give us?"

"375/968 of an acre."
