= 1/50
Wait is there any other information?
Answer:
2/3 of band practice was spent playing music.
Step-by-step explanation:
First find the common denominator.
6 times 4 is 24
8 times 3 is 24
multiply the numerators by the same value as the denominator (for 1/8 both the 1 and the 8 would be multiplied by 3, and for 1/6 both the 1 and the six would be multiplied by 4)
4/24 + 3/24
next the questions is asking for the remaining practice time.
add numerators when the denominators are the same.
4 + 3 = 7
= 7/24
24/24 - 7/24 = 16/24
(24 - 7 = 16)
now divide both the numerator and denominator by the same number.
16 ÷ 8 = 2
24 ÷ 8 = 3
The answer would be that 2/3 of band practice was spent playing music.
Answer:
The total change in value of her shares is $300
Step-by-step explanation:
Given that each share went up by $10 and she has 30 shares then the total change in the value of her shares is the product of the change in the price of each share and the total number of shares she has
= $10 * 30
= $300
