Question

find the value of-2/5+5/6(-3/5)+715)​

Answer 1

we get 715-15/30-2/5 or 715-15/30-12/30 when we convert two minus symbols into brackets, we will change the minus sign into plus sign because the amount to deduct is added by me.

we deduct 27/30 from 715 to get 714+3/30 or 714.1

The lowestcommonmultiple2of 5 and 6 is 30.
