Question

-2by3 × 3by5 + 5by2 - 3by5 × 1by6​

Answer 1

Step-by-step explanation:

(3−2×53)+25−(53×61) 

=\frac{-2}{5}+\frac{5}{2}-\frac{3}{30}=5−2+25−303

=\frac{-2}{5}+\frac{5}{2}-\frac{1}{10}=5−2+25−101

\frac{-4+25-1}{10}10−4+25−1 Taking LCM of 5, 2 and 10

=\frac{25-5}{10}=1025−5

=\frac{20}{10}=2=1020=2
