I am not sure that I answered this question right. A) 3/4 / -12=
3/4 / -11 12/12= 3/4 / - 144/12=
9/12 / -144/12= 9/12 * -12/144= -9/144=-16. B) 5/4 / 2 2/3=
15/12 / 32/12= 15/12 * 12/32= 15/32. Is this correct? Thanks
Oh my oh my for A) !!
(3/4)/(-12)
= (3/4)(-1/12)
= -1/16
B)
correct, but why are you finding common denominators for division and multiplication???
Let's go through the steps to check your answers:
A) 3/4 divided by -12:
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction:
(3/4) / -12 = 3/4 * (-1/12)
= (3 * -1) / (4 * 12)
= -3/48
= -1/16
So, the correct answer for A) is -1/16, not -16.
B) 5/4 divided by 2 2/3:
Again, we need to multiply the first fraction by the reciprocal of the second fraction:
(5/4) / (2 2/3) = 5/4 * (3/8)
= (5 * 3) / (4 * 8)
= 15/32
So, the correct answer for B) is 15/32, which matches your answer.
To avoid errors, it is helpful to simplify the fractions first, if possible. In this case, both fractions were already in simplest form, so there was no need to simplify further.
Remember, when dividing fractions, multiply the first fraction by the reciprocal of the second fraction. And always check your answer to ensure its correctness.
