Round 2.385 to 2.39

4.5 lbs of flour would cost $2.39 (D).

2.38 because  0.53 x 4.5 = 2.385 take off the 5 and your answer is c

Iwould like to think so. what’s the question you need with?

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
