Question

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

Answer 1

Answer:

Step-by-step 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)

$\frac{4}{7} + 8$ is the same as (4/7)+ (8/1). The LCM is 7. multiply each term by the LCM and divide by the denominator.

$\frac{4}{7} + 8$ =  $\frac{(4X1) + (8X7)}{7}$ = $\frac{4+56}{7}$ = $\frac{60}{7}$

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)) = $\frac{60}{7} X 7$ = 60

The answer is 60
