Question

simplify the following:-
a)120÷(-18)[20-3(9-5)]
b)64÷[16×(-3)-2]17-8​

Answer 1

Step-by-step explanation:

120 ÷ (-18) [20 - 3 (9 - 5)]

= -6,6 (20 - 3 (4) )

= - 6,6 (20 - 12)

= -6,6 (8)

= - 53,33

64 ÷ [16 × (-3) - 2] 17 - 8

= 64 ÷ (-48 - 2) 17 - 8

= 64 ÷ (-50) 17 - 8

= - 1,28 (17) - 8

= 21,76 - 8

= 13,76
