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)
[tex]\frac{4}{7} + 8[/tex] is the same as (4/7)+ (8/1). The LCM is 7. multiply each term by the LCM and divide by the denominator.
[tex]\frac{4}{7} + 8[/tex] = [tex]\frac{(4X1) + (8X7)}{7}[/tex] = [tex]\frac{4+56}{7}[/tex] = [tex]\frac{60}{7}[/tex]
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)) = [tex]\frac{60}{7} X 7[/tex] = 60
The answer is 60
