Answer:
900 L
Step-by-step explanation:
Let x be the number of litres when the tank is full.
Then 5/6 x - 30 = 4/5 x
Solve this by converting to /30:
25/30 x - 30 = 24/30 x
1/30 x = 30
x = 30*30 = 900
Let's consider each of the option
5(x-6)
5 times the difference of a number x and 6
This could be written in another way
5(6-x)
Just that one would be a positive difference and the other would be a negative difference..
The last option would have been correct but if we're to consider pedmas.. The last option is suggesting "the difference of 5 times a number and 6" which is not what the question dictates...
The penultimate option is suggesting "6 times the difference between a number and 5"
And the second option is completely astray........
Hope this helped......
AC should be 28 because 12 is 8 less than 20 and and 28 is 8 more than 20
45.2/0.2= something
we might like to make all the numbers whole numbers (1,2,3,4,5,..)
to keep fractions the same, we must multiply the top number and bottom number by the same number if we want to manipulate it
we want to move the decimal place 1 place to the right so we multiply by 10
do the same on top and bottom so 10/10 times 45.2/0.2=452/2=226
Your answer is 0.45 I think
