Answer:
Given
if p:q=2/3:3 and p:r=3/4:1/2, calculate the ratio p:q:r giving your answer in its simplest form
We need to find the ratio p:q:r
Given p:q = 2/3 : 3 = 2/3 / 3 = 2/9
and p : r = 3/4 : 1/2 = 3/4 / 1/2 = 3/2
Now p/q = 2/9 and p/r = 3/2
We need to make p equal numerators so we get
p/q = 2/9 x 3/3 = 6/27 and
p/r = 2/3 x 3/2 = 6/4
Therefore p : q : r = 6 : 27 : 4

Answer:
7. x equals 8
Step-by-step explanation:
the bigger rectangle had 4 on the side and the smaller had 2. we know dilation DO NOT occur by subtracting or adding so we can NOT conclude 4 was subtracted by 2. BUT It was DIVIDED by 2. so to check we are right..
4 divided by 2 =2
then..
16 divided by 2 = 8
Hope that helped! I could answer others but 7. was a random pick. please mark as brainliest! Thanks!
Answer:
10%
Step-by-step explanation:
Percent change= New-Old |Old|× 100% percent change=81-90 |90| × 100= -9 90×100=-10%
The answer is 0.875 just switch it to a fraction I can’t help you with everything!
