Question

[7÷3×8÷5]+[(-3÷5)×(-1÷2)]-[(-13÷9)×(-15÷2)]​

Answer 1

Answer:

u r answer is ..... -204/30

Step-by-step explanation:

=[7÷3×8÷5]+[(-3÷5)×(-1÷2)]-[(-13÷9)×(-15÷2)]

=[7*8/3*5]+[(-3*-1/5*2)]-[(-13)*-15/9*2]

=[56/15]+[(3/10)]-[(195/18)]

=[56/15]+[(3/10)]-[(65/6)]

lcm of 15 and 10 is 30

so,

=56*2/30 + 3*3/30  -65/6

=112/30+9/30-65/6

=112+9/30-65/6

=121/30-65/6

=lcm of 30 and 6  is 30 so,

=121/30-325/30

=121-325/30

-204/30
