Find the greatest three-digit number using the digits

$7, 6, 3$

0%
$763$
0%
$367$
0%
$637$
0%
$376$

Explanation

The descending order of the given numbers

$7,6,3$ is:

$7>6>3$

We observe that the smallest digit is

$3$ and the largest digit is

$7$ , so the number should start with

$7$ and end with

$3$ .

Thus, the largest number formed is

$763$ .

Hence, the greatest three digit number formed is

$763$ .

Milli starts from A and travels

$2$ km and then come back for

$280$ m. Then, the distance between point A and Milli is ?

0%
$2$ km
0%
$1$ km $720$ m
0%
$1$ km $200$ m
0%
$1$ km $100$ m

Explanation

Let us take the point of start A and point at a distant

$2$ km be B.

$AB=2$ km=

$2000$ m

As she come back 280m , we assume that point be C.

We have to find out the distance AC

$AC=AB-BC \therefore AC= 2000m - 280m = 1720m = 1$ km

$720$ m

0%
$5257$
0%
$5300$
0%
$5400$
0%
$5200$

Explanation

$\Rightarrow$ The given two numbers are

$5679$ and

$422$ .

$\Rightarrow$ In number

$5679$ , its tens digit is

$7$ , which is greater than

$5$ .

$\Rightarrow$ So, we increase the digits at hundreds place by

$1$ and replace each one of the digits at tens and ones place by

$0$ to round off the given number to its greatest place.

$\therefore$ Round off 5679 to its greatest place is

$5700$

$\Rightarrow$ In number

$422$ , its Itens digit is 2, which is less than 5.

$\Rightarrow$ So, we replace each of the tens and ones digits by 0 and keep the other digits as they are to round off the given number to its greatest.

$\therefore$ Round off 422 to its greatest place is

$400$

$\therefore$ Required number =

$5700-400=5300$

Convert the following into grams :

$24\ kg$

0%
$2,400\ gm$
0%
$24,000\ gm$
0%
$240\ gm$
0%
$24\ gm$

Explanation

We know that

$1$

$kg =1000$

$grams$

$1$

$gm =\dfrac1{1000}$

$kg$

Given That, we have to convert

$24$

$kg$ to

$gm$

$24$

$kg =24 \times 1000$

$gm$

$=24,000$

$gm$

So, option

$B$ is correct

Convert

$6\ km\ 45\ m$
0%
$60\ km\ 45\ m$
0%
$6\ km\ 450\ m$
0%
$645\ km$

Explanation

We know that

$1$

$kilo meter =1000$

$m$

$1$

$m =\dfrac1{1000}$

$km$

Given That, we have to convert

$6045$

$m$ to

$kilometer$

$6045$

$m =\dfrac1{1000} \times 6045$

$km$

$=\dfrac{6045}{1000}$

$km$

$= 6.045$

$kilo meter$

$= 6$

$km$

$45$

$m$

So, Option

$A$ is correct

Jessica walks

0%
$40$ meters
0%
$400$ meters
0%
$4000$ meters
0%
$4$ meters

Explanation

given that

Jessica walks

$2 km$ a day.

Total distance travelled by Jessica in TWO days is

$2 \times 2 =4km$

We know that

$1$

$kilometer =1000$

$m$

$1$

$m =\dfrac1{1000}$

$km$

Given That, we have to convert

$4$

$km$ into

$m$

$4$

$km =4 \times 1000$

$m$

$=4000$

$m$

So, Option

$C$ is correct

$A$ and

$C$ .

0%
$4.5$
0%
$5.5$
0%
$6.5$

Explanation

For calculating the distance between

$A$ and

$C$ , we need the sum of the distances between the points.

$AC=1+2+1+1.5=5.5$

Rosy measured a line for his art project. It is

$400$ millimeters long. How many centimeters is the line?

0%
$40$ cm
0%
$4$ cm
0%
$400$ cm
0%
$0.4$ cm

Explanation

The total length of the line is

$400$ mm.

We know that

$1$

$\text{centimeter} =10$

$\text{millimeters}$

$1$ mm

$=\dfrac1{10}$ cm

We have to convert the

$400$ mm to cm.

$400$ mm

$=\dfrac1{10} \times 400$ cm

$=\dfrac{400}{10}$ cm

$= 40$

$\text{centimeter}$

The line is

$40$ cm long.

So, option A is correct.
