So you find the common denominator which is 12.Then you convert both fractions to 12ths. 3/4=9/12 and 1/3 = 4/12.9/12 plus 4/12=13/12.
13/12 is an improper fraction so you convert into a mixed number which is 1 and 1/12.

1 1/12= answer

hope this helps!!!

First covert them to fractions with the same denominator so you can compare them (9/12 and 4/12), then subtract the numerators, and not the denominators (9/12-4/12), then whatever you get is the answer (5/12). If you can, simplify.

You have 36 pages to read for homework. In 5 minutes you read 10 page if you countinue to read at the same rate how many times w
kykrilka [37]

Answer:

18 minutes

Step-by-step explanation:

5 mins = 10 pages

10 mins = 20 pages

15 mins = 30 pages

20 mins = 40 pages

Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.

2 is the amount of pages you read in 1 minute.

so 1 minute = 2 pages

Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.

then you start adding 1 minute until you get to 36 pages.

15 minutes = 30 pages

16 minutes = 32 pages

17 minutes = 34 pages

18 minutes = 36 pages

Therefore, it should take 18 minutes to read all 36 pages.

(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)

Your teacher has 50 pencils. 9 of the pencils are green, 10 are yellow, 7 are
Fynjy0 [20]

Answer:

B. Dependent, 1/70

Step-by-step explanation:

The probability that the first pencil is yellow is 10/50.

There are now 49 pencils, so the probability that the second pencil is blue is 7/49.

There are now 48 pencils, so the probability that the third pencil is red is 24/48.

The total probability is (10/50) (7/49) (24/48) = 1/70.

Since the pencils aren't replaced after selection, each event changes the probability of the next, so the events are dependent.
