In dividing a decimal by a decimal what is 8.4 divided by 0.03 showing your work and explaining
madreJ [45]
0.03 \sqrt{8.4}

you would need to make 0.03 a whole number 1st, so you take the decimal point and move it 2 places, and you do that to 8.4.

3 \sqrt{840}


Now, divide the way you would usually do. If there is a remainder, keep adding 0's until you get the answer with no remainder. If the 0 keeps going on and on just stop after 2 0's.

Simplify: 0.9(3÷2.25− 1 8 (1 2 3 + 1 9 ))− 4 7 ÷0.8
Finger [1]

Answer:

I'm not sure if it's right but I got -2455.15

Step-by-step explanation:

You would use PEMDAS,  

( 129 + 19 ) = 148

-18 ( 148 ) =  -2664

3/2.25 = 1.333333333

1.333333333 - 2664 = -2662.666667

0.9 ( -2662.666667 ) = -2396.4

-47/8 = -58.75

-2396.4 - 58.75 = <u>-2455.15</u>
