Question

Find the value of the expression given below.

(
9/2) / (17/4) -(16/5) *-(25/68)​

Answer 1

Given: (9/2) / (17/4) - (16/5) * {- (25/68)}

To find: its value

Step-by-step explanation:

• Use BODMAS rule to find the value of the given expression.

Now, (9/2) / (17/4) - (16/5) * {- (25/68)}

= (9/2) / (17/4) + (16/5) * (25/68)

• since, {- (a)} = - (a) and (-) × (-) = (+)

= (9/2) * (4/17) + (16/5) * (25/68)

• since 1/(a/b) = 1 * (b/a)

= (36/34) + (400/340)

• where we have multiplied the respective numerators and denominators

= (360 + 400)/340

• where lcm of 34 and 340 is 340

= 760/340 = 38/17

Answer:

(9/2) / (17/4) - (16/5) * {- (25/68)} = 38/17
