<h2>1:</h2>
  • 100 ounces = 6.25 pints
  • A mile unit is equal to 1760 yards.                                                      inches =mile  * 63360                                                                                              2*63360=126720

       2 Miles = 126720 Inches

  • There are 36 inches in a yard

       3600/36= 100

       3600 inches = 100 yards

  • 1 m = 1/1000 km

       6800/1000 = 6.8

       6800 m = 6.8 km

  • 1 m = 100 cm

        15000/100=150

         15000 cm=150 m

a) Johnson ran  yard in second= 9

     1 minute = 60 second

    Johnson ran yard in one minute=  9 *60= 540 yards

b) Johnson ran  yard in second= 9

     1 hour = 60 minutes *60 second= 1200 seconds

    Johnson ran yard in one hour=  9 *1200= 10,800 yards

c) Johnson ran yard in one hour=  9 *1200= 10,800 yards

   1 mile = 1760 yards

   miles did he run in one hour= 10,800 / 1760 =6

   Johnson ran 6 mile in one hour

34 divided 5323 in simple form
joja [24]

The value when 34 is divided by 5323 is 0.00639.

<h3>What is division?</h3>

It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.

The steps include:

1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

4: Decrease the dividend's subsequent digit (if present).

5: Carry out Step 4 again.

In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.
