Answer 1

Answer:

C) is the right answer for your question

Answer 2

The product of (c) 13/2×2/3 is not equal to 1.

Given : Options

Find : Option which is not equal to 1.

Solution : Taking option 1 -

Value = $\frac{4}{5} \times \frac{5}{4}$

Cancelling 4 and 5 as both are present in numerator and denominator.

Value = 1

Taking option 2 -

Value = $\frac{8}{7} \times \frac{7}{8}$

Cancelling 7 and 8 as both are present in numerator and denominator.

Value = 1

Taking option 3 -

Value = $\frac{13}{2} \times \frac{2}{3}$

Cancelling 2 as it is present in both numerator and denominator

Value = $\frac{13}{3}$

Hence, here the value is not equal to 1.

Taking option 4 -

Value = $4 \times \frac{1}{4}$

Cancelling 4 as it is present in both numerator and denominator

Value = 1

Hence, (c) 13/2×2/3 is not equal to 1.
