Answer:
12 cups
Step-by-step explanation:
2/5 times 12 =4 4/5
Answer:
C. 2 times as long
Step-by-step explanation
8 times 10^-7 written in standard form is 0.0000008
4 times 10^-7 written in standard form is 0.0000004
divide both of them:
=2
Before attempting to solve any problem, make sure that the units are consistent. There are units of feet and inches. To be consistent,let's convert ft to in knowing that there are 12 inches in 1 ft.
9 ft*12 in/1 ft = 108 inches
Now, it also mentions that there are 5 of these. So, the total length would be:
Total Length = 108*5 = 540 inches
Finally, divide the total length to 15 inches.
Number of portions = 540/15 = <em>36 pieces of 15-inch ribbons</em>
