a b/c.
In which:
- b/c is the fractional part.
In this problem, the numbers are given as follows:

The mixed number is:
100 and 2/8 = 100 + 0.25 = 100.25.
The square root is an increasing function, hence the higher the input, the higher the square root, as 180 > 100 the comparison is:

Make denominator same first.
1/2 - 1/6
3/6 - 1/6
Now subtract numerators
(3-1) / 6
2/6
Now simplify
1/3
Final answer: 1/3
Let x be the amount of nickels and y be the amount of quarters in a jar. Totally there are 87 coins, then x+y=87.
Since nickel is 5 cent coin and quarter is 25 cent coin, then 5x+25y=1255 ($12.55=1255 cents). Solve this system:x=87-y and 5(87-y)+25y=1255.
435-5y+25y=1255,
25y-5y=1255-435,
20y=820,
y=820÷20,
y=41,
x=87-41=46.
Answer: 46 nickels and 41 quarters.
Answer:
$115.20
Step-by-step explanation:
Hi! We need to find 1% of 96 to multiply by 20.
96 / 100 = .96
Now we multiply by 20.
20 x .96 = 19.2.
Now, we add 19.2 to what she earned in the first place (96).
19.2 + 96 = 115.20
Hope this helps!
