1 answer:
a. It is rewritten as 15/4 + 4⅓
b. The fraction would be positive
c. The solution as a mixed fraction is: 8
A mixed fraction is a number that has a combination of a fraction part and a whole number. For example, 2⅓ is a mixed fraction.
Given the expression, 15 / 4 – (-4⅓), the steps below can be used to solve the fractional expression as a mixed fraction:
a. Rewrite as addition:
15/4 + 4⅓ [note, minus multiplied by minus = plus]
b. The answer would be positive because we are adding two positive fractions.
c. Solve as mixed fraction as shown below:
15/4 + 13/3
The common denominator of the two fractions is 12, thus:
= [3(15) + 4(13)]/12
= [45 + 52]/12
= 97/12
Express as mixed fraction:
97/12 = 8

Answer:
Step-by-step explanation:
We can solve this easily with proportions. If the tank is 20% full and has 500 gallons in it, when it is 100% full, it will have a proportional amount of water in it:
where the percentages are on the top and the number of gallons is on the bottom of those ratios.
Cross multiply to solve for x:
20x = 50000 so
x = 2500 gallons, max capacity
