Answer: 78% of the markers are black
Step-by-step explanation:
1. Subtract the total of markers by the amount that are blue.
a. 32-7 = 25
2. Divide the amount of black markers by the total of markers
b. 25/32 = 0.78125
3. Make this number a percentage
c. 0.78125 x 100 = 78%
Answer:
p * 90 = 36
p = 40%
Step-by-step explanation:
To find the percentage of sandwiches that are pastrami, multiply the percentage(p) by the total amount of sandwiches(90) and set it equal to the amount of pastrami sandwiches(36):
p * 90 = 36
To find the value of p, divide both sides of the equation by 90 to isolate p:
90p/90 = 36/90
p = 0.4
0.4 is the decimal form of 40%.
Hope this helps :)
