Answer:
C.
That is the closest answer since 8 times 10 6 times gets you 8 million.
Step-by-step explanation:
Answer:
since the unknown amount can buy 100 pencils
he bought 70 pencils
therefore $4.50 can buy 30 pencils
so 1 pencils cost $4.50 /30=0.15
First, you divide the 2 yard spool into 5 equal lengths, or perform the operation 2/5.
After completing this, you get that each length of ribbon is 0.4 yards. But the question asks for it in feet. (There are 3 feet in a yard) Therefore, we must multiply the number of yards by 3, to find this number in feet.
0.4*3= 1.2
Therefore, the 5 equal lengths of ribbon measure 1.2 feet.
39.0 is the decimal for it
Why they add up is because you have to add up the whole numbers and then carry over the .3 to the other side.
