koban [17]

Answer:

11/12 full

Explanation:

The correct question is

Drum X is 1/2 full of oil and drum Y, which has twice the capacity of drum X, is 2/3 full of oil. If all of the oil in drum X is poured into drum Y, then drum Y will be filled to what fraction of its capacity?

A) 3/4

B) 5/6

C) 11/12

D) 7/6

E) 11/6

Solution

Let Capacity of Drum X = 150L

and Drum Y = 300L

Oil in Drum X = 75 L

Oil in Drum Y = 2/3 * 300 = 200L

Oil poured in to Drum Y => Oil in Drum Y = 275L

Capacity Ratio = 275/300 = 11/12

What is 4/5-1/2-1/5​
zimovet [89]

Answer:

\frac{1}{10}

Explanation:

First write all numerators above the common denominator

4/5 - 1/2 - 1/2=

\frac{4-1}{5}- 1/2

Subtract the numbers

\frac{4-1}{5}- 1/2 =

\frac{3}{5} - \frac{1}{2}

Write all numerators above the least common denominator 10

\frac{3}{5} - \frac{1}{2} =

\frac{6-5}{10}

Subtract the numbers and you got your answer :)
