Hi!
When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).
Let's do an example.
16/8 : 4/6 = 16/8 * 6/4
Where necessary you can do cross-semplifying.
So, 16 and 4 can be divided both for 4.
8 and 6 both for 2.
So we have 4/4*3/1
You can also semplify numerator and denominator...
4/4 = 1
1*3 = 3
Answer:
510
Step-by-step explanation:
It's assumed 0 is not an integer.
M is obviously 2. The area of a square is the square of its side length. If this area must be an integer, then it must be the fourth integer, which is 4. The side length, 
A prime number is a positive integer which can be divided exactly by only itself and 1. In fact, it has only those two factors. The last statement excludes 1 as a prime number. Hence, the prime numbers less than 10 are 2, 3, 5 and 7. Their sum is
.

Answer:
33
Step-by-step explanation:
We know that
sin 64°= cos (x)
64° and x-------> are complementary angles
64°+x=90°
then
x=90-64----------> 26°
so
sin 64°=cos 26°
the answer is
x=26°
