Let's use equivalent decimals.
21.875 * 2.5 = _______ pounds
Pounds of nails when those nails were all used she bought 2 1/2 times as many nails as she had bought the first time how many pounds of nails did she buy the second time
21.875 * 2.5 = _______ pounds
one way is to use distributive property
(21 + 7/8)(2 + 1/2)
=(2 + 1/2)(21) +(2 + 1/2)(7/8)
= 42 + 21/2 + 7/4 + 7/16
= 42 + 168/16 + 28/16 + 7/16
= 42 + 203/16
= 42 + 12 + 11/16
= 54 11/16
Convert 21 7/8 into an improper faction of 175/8 and 2 1/2 into 5/2. Multiply together and reduce/ convert to mixed fraction of 54 11/16.
What are you dividing? What is the answer?
She bought more than twice as many nails the second time.
Did she buy over 54 pounds or almost 9 pounds the second time?
