Given that Sara put 7 boxes in her closet.
So number of boxes = 7
Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.
So the number of seashell in 1 box = 0
We need to find about how many shells does Sara have.
To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.
we know that product of a number and 0 is always 0.
Hence final answer is 0 seashell.
B. I know that 50 ÷ 40 = 5454, 5 ÷ 4 = 1 1/4, so I read 1 1/4 more pages than my sister reads in 1/2 hour.
C. Because I read 10 more pages than my sister reads in 1 hour, I read 5 more pages in 1/2 hour.
D. Since 5 • 4 = 20, I read 20 more pages than my sister reads in 1/2 one half hour.
