Question

How do you work out the math problem ( 1+19÷12 ) t-1

Answer 1

well......

you always do multiplication/division first (when parenthesis are involved, do what's in parentheses first following that same rule in this case)

19 ÷ 12 can't be reduced to a whole number or a simplifies fraction so you're stuck with 19/12

1 + (19/12) = (12/12) + (19/12) = 31/12
This fraction also can't be reduced.

ok, so that's what's in the parentheses.

(31/12)t - 1


If you need to solve for t:
set equation to 0


(31/12)t - 1 = 0
(31/12)t = 1
(31/12)t • (12/31) = 1 • (12/31)
t = 12/31

Assuming it is (1+19÷12)(t-1):

it is still (31/12)
(31/12)(t-1)

multiply the terms in the parenthesis:

(31t/12) - (31/12)

if solving for t:
set equation for 0 and do not multiply the terms together:

(31/12)(t-1) = 0
(12/31) • (31/12)(t-1) = 0 • (12/31)
multiplying anything by 0 is 0.
t-1 = 0
t=1

Answer 2

If you are simplifying the equation (1+19÷12)t-1, then the answer is 2.5833...t - 1. Look at the picture for an explanation.
