Answer:
21
Step-by-step explanation:
Find 60% of 35.
To do this you have to multiply 60 by 35, and divide that answer by 100, and your answer should that number. In this case, the answer is 21, because 60x35 is 2100, and 2100/100 is 21.
Answer:
turn the decimal into a whole number by multiplying by 10, 100 (what you do to one number you must do to the other)
multiply both by 10 it then becomes
540/75 = 7.2
it's easier to divide whole numbers and is the same answer as 54/7.5
Answer:
16
Step-by-step explanation:
x+y=30 solve for x x=30-y
substitute x with 30-y and solve
11.25x+22.4y=515.9
11.25(30-y)+22.4y=515.9
337.5+11.15y=515.9
11.15y=178.4
y=16
since we're solving for just large candles it's 16
if need small cangle number 30-16=14
Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
