Answer:
3/2
Step-by-step explanation:
to divide fractions you just have to multiply them by the reciprocal.
so, instead of 3/4 divided by 1/2
it's changed to 3/4 * 2/1
then you just multiply the numerators together and the denominators together
3*2/4*1
6/4
3/2
3/2
Goodluck with your schoolwork/homework.

The Answer: D.Ray
Explanation:
Answer:
311.6 cm
Step-by-step explanation:
To solve this problem, let's call:
k = Keith's height
n = nephew's height
Since the ratio is 15:7, we have
(1)
Then, Keith's height is increased by 16%, so the new height of Keith is
(2)
While the nephew's height is doubled:
(3)
We also know that Keith is now 34 cm taller than his nephew, so
(4)
Substituting (2) and (3) into (4), we get
And substituting (1),
Solving for n,
So the current height of the nephew is:
While Keith's current height is
So their total current height is
Answer:
A. 72
Step-by-step explanation:
Determinant of a 2x2 matrix: ad - bc
In that case,
24(18) - 30(12)
432 - 360
72
And we have our answer.
