Last week, janet used 4 cups of flour to make pizza dough. this week, she uses 3/8 the amount of flour as last week. which statement is true about the amount of flour that janet uses this week?

The answer is D

First, let's find the amount of flour she used. (So it makes more sense)

4/8= 1/2

3*1/2= 1.5

Janet uses 1 and 1/2 cups of flour this week.

That is less than four cups, so we can eliminate statement A and B.

It is not less than one though because 1.5>1

"C" is the correct answer. She uses less than four cups because 3/8 (1.5) is less than 4.

I hope this helps!
