the correct answer is 34square

Answer 2

Step-by-step explanation:

$\dfrac {16}{35} \times \: \dfrac{21}{48}$

We know that 16×3 = 48. Cancel it from denominator and numerator.

$\dfrac { \cancel{16}}{35} \times \: \dfrac{21}{ \cancel{48} }$

$\dfrac {1}{35} \times \: \dfrac{21}{3}$

Now 3×7 is 21 cancel from both numerator and denominator.

$\dfrac {1}{35} \times \: \cancel \dfrac{21}{3}$

$\dfrac {1}{35} \times \: \dfrac{7}{1}$

7×5=35 Cancel from numerator and denominator.

$\cancel{\dfrac {1}{35} \times \: \dfrac{7}{1} }$

$\dfrac{1}{5}$
