Jalen bought 9/16 pound of blue cheese at the deli. he also bought 1 3/16 pounds of swiss cheese. he estimates that the he bought about 1 3/4 pounds of cheese altogether. which best describes jalen's estimate?
a. it is not reasonable because 9/16 is about 3/4 and 1 3/16 is about 1 1/2, and 3/4 + 1 1/2 = 2 1/4.
b. it is reasonable because 9/16 is about 1/2 and 1 3/16 is about 1 1/4, and 1/2 + 1 1/4=1 3/4.
c. it is not reasonable because 9/16 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2.
d. it is reasonable because 9/12 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2/2, which is about 1 3/4.
