<u>-7/4 or -1 3/4</u>
Step-by-step explanation:
Step 1. Convert into improper fraction.
2 1/2 = 5/2
Step 2. Convert the fractions into common denominator.

Answer:
16
Step-by-step explanation:
Let the number be X
3/4 of X = 15
Multiplying out gives;
3X = 4x15
3X= 60
X = 20
Therefore, 4/5 of 20
Putting X = 20 we have;
4/5 x 20 = 16.

Step-by-step explanation:
<h3>
Answer: A = 43 degrees</h3>
Explanation:
The rule used here is
if sin(A) = cos(B), then A+B = 90.
In this case, B = 47, meaning that,
A+B = 90
A+47 = 90
A = 90-47
A = 43
Therefore,
sin(43) = cos(47)
