0.25 X 360 = 90
To mulyply decimals by long multiplication.
360
x 25 ( NB we have temporarily dropped the decimal point).
7200 (360 x 20)
1800 (360 x 5)
9000
=====
We note that there were only 2 decimals places in the multiplicands. So the answer has 2 decimal places.
Hence 9000 becomes , 90,00 or just plain '90'.
Another way is to note that ' 0.25 = 1/4'
So again multiply 360 x 1/4
Multiplication of fractions.
360/1 x 1/4 =
Cancel down by '4'
90/1 X 1/1 = 90/1 = 90
Another 'Short Circuit' method. is to note that 9 x 4 = 36
Hence 90 x 4 = 360
So 360/ 4 - 360 x 1/4 = 90 .
Careful with this last method, 'Short Circuits; can be dangerous, mabd so you my end up with the wrong answer.
15x = 360 Algebrauically rearrange x = 360/15 Cancel down by '5' x = 72/3 Cancel down by '3' x = 24/1 x = 24 The answer!!!!!
5 x Y = 360 360 / 5 = Y Answer: 72
2 x 2 x 2 x 3 x 3 x 5 = 360
(18 x 20) = 360 That's 36 tens. You could look at it this way: 20 = 2 tens; 18 x (2 tens) = (18 x 2) tens = (36) tens
If 5 x equals 9 plus 2x then x equals?
15x = 360 Algebrauically rearrange x = 360/15 Cancel down by '5' x = 72/3 Cancel down by '3' x = 24/1 x = 24 The answer!!!!!
x - 360 = 270 x = 270 + 360 x = 630
9 x 4 x 10 = 360
180 X 2 = 360
x = 104
18,000
5 x Y = 360 360 / 5 = Y Answer: 72
360/2= 180 so 180 x 2 = 360 more examples - 60 x 4 =360 36 x 10= 360 360x 1 = 360
x=-12
Easy, 360!
5 x Y = 360 360 / 5 = Y Answer: 72
60 x 6 = 360
