Question

Evaluate (4/7 + 8) x (3-(-4))

Answer 1

Explanation:

To solve the question, apply BODMAS approach. that is solve the brackets, division, multiplication first before the addition and subtraction.

step 1: take the first bracket (4/7 + 8)

`(4)/(7) + 8` is the same as (4/7)+ (8/1). The LCM is 7. multiply each term by the LCM and divide by the denominator.

`(4)/(7) + 8` =
`((4X1) + (8X7))/(7)` =
`(4+56)/(7)` =
`(60)/(7)`

step 2: consider the second bracket (3-(-4))

there is a sign multiplication in the terms. minus (-) x minus (-) = plus (+)

therefore the second bracket (3-(-4)) = 3 + 4 = 7

step 3: multiply both brackets.

(4/7 + 8) x (3-(-4)) =
`(60)/(7) X 7` = 60

The answer is 60
