1$$\frac{1}{6}$$ = (6 + 1)/6 = 7/6
1$$\frac{1}{6}$$ + $$\frac{1}{3}$$
= 7/6 + 1/3
= (7 +2)/6
= 9/6
= 3/2 or 1 1/2
Explanation:
Perform addition operation on given numbers. The mixed fraction 1 1/6 in fraction form as 7/6. Add 7/6 with 1/3 the sum is 3/2.

Question 6.
Write the next number in the sequence. 3,064; 3,014; 2,964;
The given sequence is 3,064; 3,014; 2,964.
The difference between first two numbers in the sequence is 50.
3,064 – 3014 = 50
The difference between second two numbers in the sequence is 50.
3,014 -2964 = 50
So, subtract 50 from the next number in the sequence number 2,964 the difference is 2,914.
2,964 – 50 = 2,914
The next number in the sequence is 3,064; 3,014; 2,964; 2,914.

Question 9.
Calculate the volume of a rectangular prism that has side lengths of 6 cm, 4 cm, and 2 cm.
Given side lengths = 6 cm, 4 cm, and 2 cm
Volume of a Rectangular Prism = length Ã— base Ã— height
We know the side lengths
V = 6 Ã— 4 Ã— 2
V = 48 cm3

Question 10.
Is a 145Â° angle obtuse, reflex, or straight?
145Â° is a obtuse angle.
Explanation:
Obtuse angle:
The obtuse angle is greater than 90 degrees and less than 180 degrees.
Reflex angle:
The reflex angle is greater than 180 degrees but less than 360 degrees.
Straight angle:
A straight angle is 180 degrees.

Question 11.
What is the mode of this set of data?
601, 611, 621, 611, 631
The given sequence is 601, 611, 621, 611, 631.
Mode is defined as the number that occurs more number of times.
The number 601 occurs 1 time.
The number 611 occurs 2 times.
The number 621 occurs 1 time.
The number 631 occurs 1 time.
The mode of the given set of data is 611.

Question 12.
I am part of a whole, I am greater than one-tenth but less than 13%. My denominator is 8. What number am I?
one-tenth = 0.1
13% = 0.13
0.1 > x < 0.13
9/8 = 0.125
So, the unknown number is 0.125
