, you will get -

Discuss Question

Answer: Option B. -> 2
:
B
The fractions

\frac{35}{9}

and

\frac{53}{9}

are like fractions, as they have same denominator.
To subtract like fractions, we have to subtract only the numerators and keep the denominator same.

\frac{53}{9} - \frac{35}{9} = \frac{53 - 35}{9} = \frac{18}{9} = 2

Question 34. Determine the numerator and denominator in this fraction:

\frac{2}{7}

Numerator = 7; Denominator = 2
Numerator = 2; Denominator = 7
Numerator = 14; Denominator = 4
Numerator = 4; Denominator = 14

Discuss Question

Answer: Option B. -> Numerator = 2; Denominator = 7
:
B
This is the example of proper fraction.
The numberabove the line in a proper/improper fractionis called the numerator and the numberbelow the line is called the denominator.
Hence, here the numerator 2 is and the denominator is 7.

Question 35. Represent

13 + \frac{7}{10} + \frac{3}{1000}

True
False
1476
1716

Discuss Question

Answer: Option A. -> True
:
A
Two equivalent fractions can never have same denominators. And like fractions have same denominators. So, two equivalent fractions can never be like fractions.
