Question

Simplify the following
a) 5/6×2/3×-18/15
b) 22/21÷-33/42​

Answer 1

Answer:

-2/3

Step-by-step explanation:

$\frac{5}{6} \times \frac{2}{3} \times \frac{ - 18}{15}$

$\frac{5 \times 2 \times ( -6)(3)}{6 \times 3 \times 5 \times 3}$

cancel the same numbers in numerator and denominator

$\frac{ - 2}{3}$
