1. Are 4/8 and 6/12 Equivalent Rational Numbers?
Solution:
If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal
4*12 = 48
8*6 = 48
Therefore, 4/8 and 6/12 are Equivalent Rational Numbers.
2. Express Rational Number 8/5 with a Numerator 56?
Solution:
In Order to Express Rational Number 8/5 with a Numerator 56
Numerator = 56
To make the rational number 8/5 with a numerator 56 firstly we need to divide the 56 by 8 i.e. 7
Multiply with 7 both the numerator and denominator of rational number 8/5
= 8/5*7/7
= 56/35
Thus, Rational Number 8/5 can be expressed as 56/35 with a numerator 56.
3. Are 3/7 and 4/5 Equivalent Rational Numbers?
Solution:
If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal.
3*5 = 15
7*4 = 28
Thus 15 ‰ 28
Therefore, 3/7 and 4/5 are Not Equivalent Rational Numbers.
4. Express Rational Number 3/7 with a Denominator 49?
Solution:
To write the rational number 3/7 with a denominator 49
we need to find the number that when multiplied results in denominator 49
49/7 = 7
Multiply with 7 both the numerator and denominator of the rational number 3/7
= 3/7*7/7
= 3*7/7*7
= 21/49
5. If p/q = m/n then which of the following is true is always true?
a)n/m = p/q b)p*q=m*n c)p/n = m/q d)p*n = m*q
Solution:
d)p*n=m*q
If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal.
6. A Rational Number Equivalent to 2/1 is
a)10/-5 b)10/5 c)-10/5 d) None of the above
Solution:
b) 10/5
2/1 = 2*5/1*5
= 10/5
Therefore Rational Number Equivalent to 2/1 is 10/5
7. What is the Rational Number Equivalent to 5/8
a)25/40 b) 25/-40 c)-25/40 d)None of the above
Solution:
a) 25/40
5/8 = 5*5/8*5
= 25/40
Rational Number Equivalent to 5/8 is 25/40
8. Fill in the blank to make Two Rational Numbers Equivalent
a) 4/7 = …./56
Solution:
32
In order to make the Rational Number 4/7 with denominator 56 we have
4/7 *8/8 = 32/56
Therefore, 4/7 is Equivalent to the Rational Number 32/56.
9. If 1/x = -x/1 then x is ……..
a) Whole Number b) Natural Number c) Rational Number d) Not a Rational Number
Solution:
d) Not a Rational Number
1/x= -x/1
-x2 = 1
x2 = -1
x= ˆš -1
Therefore, x is not a Rational Number.
10. Select the rational numbers which can be written as a rational number with denominator 4 from the following
7/3, 64/11, 30/(-12), (-16)/17, 5/(-4), 140/28
Solution:
30/(-12), 5/(-4), 140/28
Since all the above options can be rearranged to get a Rational Number with the Denominator 4.
