Question 4.
Select all the expressions that have the same value as 3.75 – 2.63.
(A) 4 – 2.38
(B) 4 – 2.88
(C) 3 – 1.88
(D) (3 – 2) – (0.75 – 0.63)
(E) (3 – 2) + (0.75 – 0.63)
Answer:
(B) 4 – 2.88,
(C) 3 – 1.88,
(E) (3 – 2) + (0.75 – 0.63),
Explanation:
Given to select all the expressions that have
the same value as 3.75 – 2.63, So it is
3.75
-2.63
1.12
Checking with bit (A) 4 – 2.38 = 1.62 which will not match,
checking with bit (B) 4 – 2.88 = 1.12 matches,
checking with bit (C) 3 – 1.88 = 1.12 matches,
checking with bit (D) (3 – 2) – (0.75 – 0.63) = 1 – 0.12 = 0.88
which will not match,
checking with bit (E) (3 – 2) + (0.75 – 0.63) = 1 + 0.12 = 1.12 matches,
Therefore bits (B) 4 – 2.88, (C) 3 – 1.88, (E) (3 – 2) + (0.75 – 0.63).
Question 5.

28.4
+9.38
19.02
Question 7.
Which represents the sum 1.3 + 0.46?
(A) 1.76
(B) 1.94
(C) 5.36
(D) 5.9
Answer:
(A) 1.76,
Explanation:
The sum of 1.3 + 0.46 is
1.30
+0.46
1.76 which matches with bit (A).
Question 8.
How would you explain to someone how to subtract 3.85 from 9.2? What is the difference?
Answer:
The difference is 5.35,
Explanation:
Subtracting 3.85 from 9.2 first
we subtract decimal values hundredths and tenths as
9.20
-3.85
5.35.
Question 9.
Select all the expressions that have a value of 28.02.
(A) 13.75 + 14.27
(B) 13.75 + 14.25 + 0.02
(C) 13.78 + 14.30
(D) 13.78 + 14.30 + 0.03
(E) 27 + 1 + 0.02
Answer:
(A) 13.75 + 14.27,
(B) 13.75 + 14.25 + 0.02 and
(E) 27 + 1 + 0.02,
Explanation:
The expressions that have a value of 28.02,
Checking with bit (A) 13.75 + 14.27 = 28.02 matches,
Checking with bit (B) 13.75 + 14.25 + 0.02 = 28.02 matches,
Checking with bit (C) 13.78 + 14.30 = 28.08
which is not matching,
Checking with bit (D) 13.78 + 14.30 + 0.03 = 28.11
which is not matching,
Checking with bit (E) 27 + 1 + 0.02 = 28.02 matches,
theerfore bits (A) 13.75 + 14.27,
(B) 13.75 + 14.25 + 0.02 and
(E) 27 + 1 + 0.02 matches.
Question 10.
Joe’s rabbit weighs 1.35 pounds. Dale’s rabbit weighs 0.68 pound. How much more does Joe’s rabbit weigh?
