Answer:
your closest number should be A
Answer:
Step-by-step explanation:
When you are changing a repeating decimal to a fraction, there is a trick you have to know. 2 actually. Put the decimal right before the repeating starts and right after the repeating starts. This one is a bit tricky since the decimal is after a 1, and 1 is what is repeating. So let's leave that one as is and simply say that
x = -1.11111
Now let's move the decimal right after the second one. To do that you have to multiply by 10. So we then can say that
10x = -11.11111
For this problem, we will disregard the negative til the end because it just makes things confusing.
Subtract the smaller equation from the larger:
10x = 11.111111
- 1x = 1.111111
and get
9x = 10
Divide both sides by 9 to get 10/9 which is 1 1/9 as a mixed fraction. Let's check it first to see if we're correct, then we'll throw the negative sign back on.
10/9 on your calculator gives you 1.111111111 repeating, so now that we know we are correct, the mixed fraction is
-1 1/9
(10+6) / 8+2-4=0
10 plus 6 equal 16, divided by 8 plus 2 minus 4 equal 0
Answer:
495-75=m m=420
Step-by-step explanation:
He needs to save 495 dollars, and hes already saved 75
and needs to find out how much more he needs to save to have 495 dollars
To do this, take 495 and subtract 75. This is how we get the inequality
495-75=m
From here it is simple, just subtract 75 from 495 to get 420
25% of the 9th grade belongs to more than one club.
9th grade population 180
1 club = 90
2 clubs = 33
3 or more clubs <u>= 12</u>
Students w/ clubs 135
2 clubs + 3 or more clubs = 33 + 12 = 45 ÷ 180 = 0.25 x 100% = 25%
1 club = 90 ÷ 180 = 0.50 x 100% = 50%
no club = 180 - 135 = 45 ÷ 180 = 0.25 x 100% = 25%
