The value of the given expression is -121/ 30.
BODMAS stands for Bracket Of Division Multiplication Addition and Subtraction. It is basically the rule of the order in which a mathematical expression must be solved.
Here, we are given an expression- -2/3 (1.5 ÷ 0.25 ÷ 5/4) -5/6
It can be written as -2/3 (15/10 ÷ 25/ 100 ÷ 5/4) -5/6
= -2/3 (3/2 ÷ 1/4 ÷ 5/4) -5/6
As per the rules of BODMAS, we first deal with the terms inside the bracket-
(3/2 ÷ 1/4 ÷ 5/4) = (3/2 × 4 × 4/5)
= (3 × 2 × 4/5)
= 24/5
Thus, the expression becomes-
-2/3 (24/5) -5/6
= -48/ 15 - 5/6
LCM of 15 and 6 is 60
⇒ -(48 × 4)/ 60 - (5 × 10)/ 60
-192/ 60 - 50/ 60
= (-192 - 50)/ 60
= -242/ 60
= -121/ 30
