To find the difference of given expression:

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

First step is to subtract the whole number5 and 3.

So, 5 - 3 = 2.

Now we can find the difference of fractions.

To subtract the fractions , we need to find the common denominator.

Common denominator of 3 and 5 is 15.

So, we need to make both the denominator equal to 15.

\frac{2}{3} =\frac{2*5}{3*5} =\frac{10}{15}

Similarly, \frac{1}{5} =\frac{1*3}{3*5} = \frac{3}{15}

Therefore, \frac{2}{3} -\frac{1}{5} =\frac{10}{15} -\frac{3}{15}

=\frac{10-3}{15}

= \frac{7}{15}

So, the difference of given expression is 2\frac{7}{15}.

So, the correct choice is C.

A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solu
nlexa [21]

Step-by-step explanation:

If x = the amount of 12% and y = the amount of 20%, then x + y = 80

Since we need 80 grams of 15%, 80(.15) = 12.

We are given that .12x + .20y = 12.

We can solve the first equation for x or y. Let's do x.

x = 80 - y

.12(80 - y) + .20y = 12

9.6 - .12y + .20y = 12

.08y = 2.4

y = 30

x = 80 - 30 = 50
