Find the difference 5 2/3 - 3 1/5 A. 5 2/3 B. 8 13/15 C. 2 7/15 D. 3 1/5

RSB [31]

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.

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch lon

Lady_Fox [76]

Answer:

Combined volume of the two game systems $=416$ cubic inches

Step-by-step explanation:

Volume of a cuboid = length × breadth × height

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.

So,

Volume of Soham's video game system = 8 × 6 × 2 = $96$ cubic inches

As Sean's video game system measures 1 inch longer on all sides,

the video game system measures $8+2=10$ inches long, $6+2=8$ inches wide, and $2+2=4$ inches tall.

Volume of the video game system = 10 × 8 × 4 = $320$ cubic inches.

Therefore,

Combined volume of the two game systems = $96+320=416$ cubic inches
