Question

how to multiply 1500*80/10

Answer 1

first multiply 15 x 8 and put as much zero as both numbers have like 15 x 8 = 120 and then total 3 zeros (1500, 80) so its 120000.

Now divide it with 10. just cross 1 zero as its only one zero in 10. So it will be 12000.

Answer 2

first divide 80 with 10 then multiply 8 with 1500.
the answer will be 12000.....
