@Moo
some of the questions are different for each person so that why the answer for one was different for you :) it’s a unit test so it makes sense that they are different to avoid cheating (won’t stop me tho >:)
if you just type the actual answer instead of ABC or D then evryone would actualy get it right
School sucks isn’t correct
every bodys Questions are diffrent
(the first two are open ended, so is the last one)
3: 0.68 can be simplified to 17/25
4: 14 students have 7 pizzas cut into 8 slices, each student will have 1/2 a pizza
5: 8^-2 = 1/64
6: in 2012 the population of florida was 3,158,697. as scientific notation it’s approximately 3.2x10^6
7: (4x10^3) x (3x10^4) as scientific notation is 1.2 x 10^8
8:there is 1/6 of a cake and Mitchell only wants 3/12, they want 1/24 of the cake
9: Dory bought 2 computers, each cost $210.99 and he sold them for $240.00 each, his profit was 58.02
10: 0.00000512 as scientific notation is 5.12x10^-6
11: 31/5 as a decimal is 6.2
12: 2010 census shows the population for texas, florida, and idaho, the true statement is that idaho has the smallest population
13: 3.56x10^-5 is stander form is 0.0000356
14: 3.141592... is the irrational number
15: 0.7 repeating is 7/9 as a fraction
16: ben spent 2/3 of his allowance, the decimal equivalent is 0.6 repeating
17: ashley need 3/4 cups of sugar five times for five batches of cookies, she needs 3 3/4 cups of sugar
18: -1/6 + (-3/7)= -25/42
19: idk i got it wrong but the question was 9/13 +(-2/5) =?? (it’s not -7/65 i’ll tell you that)
20: 5 1/3 - 3 4/7= 1 16/21
21: 1/2 x -1/3 = -1/6
22: 5/8 divided by 15/16 = 2/3
23: 3 1/2 yd is the length of a ribbon, joy needs to cut 1 5/9 yd long pieces, she can cut 2 pieces
24: 1 2/5 divided by 2 1/3 = 3/5
the questions are probably not going to be in order for everyone but try to use the parts of the question i put in the answers to find where they belong on your test if i got anything wrong please tell me
good luck!!
i know Steve it's really weird that my questions are like this but they are.
thanks for helping man.
what if idk we actually put answers instead of just letters!! i think they are putting the answers in different orders for different students, i may be wrong tho, i’ll take the test and put the answers i got correct as the actual numbers soooo yeah (it’s for the 8th grade 2020 unit 3 test part one for future reference)

Well is it correct?
Is cat right?
sorry meant 1,000,000
Why do you multiply to find the answer to question 8? I also got #8 wrong because I didn't know how to solve it. Can you explain it or tell me where to look to find the right way of completing the problem?
I just used right kids answer and got 100%. Thanks so much bro. Works for connects
#4. c
14 students, 7 pizzas. Doesn't matter how many slices they use.
#5. Not sure, since you botched the exponent. However,
8^2 = 64
8^-2 = 1/64
#6. (a) There are 8 decimal places after the 3.
#7 (a)
3*10^2 x 5*10^5 = 15*10^7 = 1.5*10^8
#8. (d)
1/4 * 2/3 = 2/12 = 1/6
#10. (b)
.387 = 3.87*10^-1
shift left 5 more places and you have 3.87*10^-6
#13. (c)
#15,16 correct, if the final digit repeats.
#18. (d)
#20. (c)
5 1/3 - 3 4/7 = 16/3 - 25/7 = 112/21 - 75/21 = 37/21 = 1 16/21
#22. (c)
7/8 * 12/11 = 84/88 = 21/22
The rest look correct.
Looks like you need to review some more, especially scientific notation.
Plus, what's all the nonsense with words? Real people use digits when talking about numbers. That, and the typos made it hard going.
-2/3 - 3/10 = -(2/3 + 3/10) = -(20/20 + 9/30) = -29/30
