7.D is the correct answer. I simplified 12/27 to 4/9 then i try to see if 4/9 is equivalent to 20/45 and it is you multiply 4 and 9 by 5= 20/45

8. 1.4*2.1=2.94 then 2.94/1.5= 1.96 so c=1.96

9. Explanation You multiply- 5/8 * 3/5 then divide = answer divided by 2/3

Solving: 5/8*3/5= 3/8 then 3/8 divided by  2/3, flip second number and then switch the division sign to multiplication sign so it should be like this : 3/8 * 3/2= 9/16
answer= 9/16

20% of what number is 30? Pick the proportion that could be used to solve.
Colt1911 [192]

30 is 20% of 150

Working out percentage problems of the form "30 is 20 percent of what number?"

We have, 20% × x = 30

or,  

20/100 × x = 30

Multiplying both sides by 100 and dividing both sides by 20,

we have x = 30 ×  100/20

x = 150

If you are using a calculator, simply enter 30×100÷20, which will give you the answer.

What is the difference between a defined and an undefined term in Geometry?
Flura [38]
The difference between defined and an undefined term in Geometry is that defined terms can be combined with each other or an undefined term, and by doing this, there is another term defined. For example, an angle is a combination of two rays, which is an undefined term. Undefined term on the other hand is used to define other terms.
