Answer:
7.22 x 10^5
Step-by-step explanation:
Remember that the decimal is always to the right of the ones place.
1. Move it one place to the left and multiply by 10 to compensate.
2. Move it two places to left and multiply by 10^2.
3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.
4. Numbers after the 7 that are not zeros will be after the decimal point.
so, 7.22 x 10^5

Answer:

Step-by-step explanation:
to find 19/6 located where on the number line
first we need to convert 19/6 to decimal
19/6 = 3.166...
so lets now see where 3.166 lies
it first lies between 3.160 and 3.170
but we need integer
so we go deeper and see
it lies between 3.100 and 3.200
and then we need to go more deeper to get an integer not decimal
now it lies between 3 and 4
