Perform the operation and write the answer in simplest form. 2 1/5 ÷ 31/5

Vinil7 [7]

Answer:

$\frac{11}{31}$

Step-by-step explanation:

We are given the following expression and we are to perform operation and write the answer in simplest form:

$\frac { 2 \frac { 1 } { 5 } } { \frac { 31 } { 5 } }$

Changing the mixed fraction into improper fraction:

$2\frac{1}{5}$ ---> $\frac{11}{5}$

Now simplifying it:

$\frac { \frac { 1 1 } { 5 } } { \frac { 31 } { 5 } }$

Changing the division sign to multiplication by taking the reciprocal of the denominator:

$\frac{11}{5} \times \frac{5}{31}$

$\frac{11}{31}$

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>
