Arrange the steps to perform this subtraction operation in the correct order.
taurus [48]

Answer:

=1.23*10^6

Step-by-step explanation:

We have to calculate

(1.93*10^7 )-(9.7*10^6)

In order to add or subtract two numbers in scientific notation, we have to make sure that the power of exponents in both numbers is same.

We have to reduce the power of 10 in first number from 7 to 6

So,  

Step 1:

1.93*10^7=1.93*10*10^6

=10.93*10^6

Now,

Step 2:

=(1.93*10^7 )-(9.7*10^6 )

= 10.93*10^6- 9.7*10^6

Step 3:

=(10.93-9.7)*10^6

=1.23*10^6

46. Merchandising If 12 items are in a dozen, 12 dozen are in a gross, and 12 gross are in a great-gross, how many items are in
Andrews [41]

Answer: 1728

Step-by-step explanation: You multiply 12 times 12 because we have to find how many items are in a 12 dozen first which is 144 because there are 12 items in one dozen.  We already know that there are 144 items in 12 dozens and there are 12 dozens in a gross, which is 144 items in total. Now we have to multiply 144 times 12 to find how many items are in a great gross. 144 times 12 is 1728.
