Answer» Follow BODMAS rule to solve this question, as per the order given below, Step -1- Parts of an EQUATION enclosed in 'Brackets' must be solved FIRST, and in the bracket, Step -2- Any MATHEMATICAL 'Of' or 'Exponent' must be solved next, Step -3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step -4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. Given expression is, ? – 7/18 = 17/10 – ? ⇒ ? + ? = 17/10 + 7/18 ⇒ 2 × ? = [(17 × 9) + (7 × 5)]/ 90 ⇒ 2 × ? = (153 + 35) /90 ⇒ 2 × ? = 188/90 ∴ ? = 188/180

Answer»

Follow BODMAS rule to solve this question, as per the order given below,

Step -1- Parts of an EQUATION enclosed in 'Brackets' must be solved FIRST, and in the bracket,

Step -2- Any MATHEMATICAL 'Of' or 'Exponent' must be solved next,

Step -3- Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step -4- Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Given expression is,

? – 7/18 = 17/10 – ?

⇒ ? + ? = 17/10 + 7/18

⇒ 2 × ? = [(17 × 9) + (7 × 5)]/ 90

⇒ 2 × ? = (153 + 35) /90

⇒ 2 × ? = 188/90

∴ ? = 188/180
