What is <br>2/3 of 1/4 of x = 1360

Murljashka [212]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 8160}}}}}$

Step-by-step explanation:

$\sf{ \frac{2}{3} \times \frac{1}{4} \times x = 1360}$

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term

$\longrightarrow{ \sf{ \frac{2 \times 1}{3 \times 4} \times x = 1360}}$
