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:
1/2
Step-by-step explanation:
The rise of the slope is 1
The run of the slope is 2
I think it's x= -2.5
10/-4= -4x/-4
You need to get x by itself so you need to divide 4 in each side . Shown above
Their ages are x, 2x, 3x, 4x, 5x.
The oldest is 16 years older than the youngest. There are 5 daughters.
<span>5x-x=16. 4x=16 x=4
</span>
Their ages are 4 , 8 , 12 ,16 , 20
Answer:
9 is the right answer
Step-by-step explanation:
I. If c = - 4 and d = 10
then 
= 
= 
= 9
Hope that help :D
