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

Answer: 75 is a composite number. 75 = 1 x 75, 3 x 25, or 5 x 15. Factors of 75: 1, 3, 5, 15, 25, 75. Prime factorization: 75 = 3 x 5 x 5, which can also be written 75 = 3 x 5².
Answer:
the answer to the second one is (205 - 15)/2.
Lilly has 110.
Severus has 95.
Step-by-step explanation:
Because 205-15 = 190 so if you divide that by 2 then you will get the amount that Severus had which is 95 meaning that Lilly also has 95 but since she has 15 points higher then she has 110 so 95+110=205.
