There are 12 face cards and 4 fours in a deck so 16/52 total which can be simplified to
4/13
Answer:
8/12, 3/12
Step-by-step explanation:
Least common multiple for 3 and 4 is 12. So the denominator should be 12.
For the fraction 2/3, multiply the numerator and denominator by 4 so you will get :
2/3 * 4/4 = 8/12
For the fraction 1/4, multiply the number and denominator by 3 so you will get:
1/4 * 3/3 = 3/12
Let x be the fifth number
⇔
⇔ 23.3 + x = 34
⇔ x = 10.7
i don't know people are rude lol I tried at least
Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
