Answer :
1 3/8 lbs. 2 1/2 = 2 4/8. (8/8 is 1 lb) 2 4/8 + 8/8 = 3 4/8 add 3/8 to equal 3 7/8. You have added 1 3/8 lb to 2 1/2 lb to make 3 7/8 lbs.
Answer:
B. No, the answer is not reasonable. It should be a bit more than 1 1/2 pounds.
Step-by-step explanation:
We have been given that Gino has [tex]3\frac{7}{8}[/tex] pounds of grapes. He has [tex]2\frac{1}{4}[/tex] pounds of green grapes and the rest are red grapes. A student solved this problem and said the answer is [tex]\frac{5}{8}[/tex] pounds.
Let us solve the given problem by subtracting [tex]2\frac{1}{4}[/tex] from [tex]3\frac{7}{8}[/tex].
[tex]3\frac{7}{8}-2\frac{1}{4}[/tex]
[tex]\frac{3*8+7}{8}-\frac{2*4+1}{4}[/tex]
[tex]\frac{31}{8}-\frac{9}{4}[/tex]
[tex]\frac{31}{8}-\frac{9*2}{4*2}[/tex]
[tex]\frac{31}{8}-\frac{18}{8}[/tex]
[tex]\frac{31-18}{8}[/tex]
[tex]\frac{13}{8}[/tex]
[tex]1\frac{5}{8}[/tex]
Since [tex]1\frac{5}{8}[/tex] is greater than [tex]1\frac{1}{2}[/tex], therefore, option B is the correct choice.
