I wouldn't say that. It looks to me like you've absolutely got it ... almost.
A). Your fraction is correct. But it's not in simplest form like they want it.
Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .
B). They want the percentage that's the same as 18/45 .
Do you remember how to change a fraction to percent ?
A fraction is just a short way to say "division".
" 18/45 " means " 18 divided by 45 ".
Do the division. To change the quotient into percent, multiply it by 100 .
(Same as moving the decimal point 2 places to the right.)
Round it the nearest whole number, if it isn't already a whole number.
C). Again, your fraction is correct, but it isn't in simplest form.
Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.
D). Change this fraction to percent, just like you did for the female fraction.
(Do the division that the fraction says, and multiply the quotient by 100.)
(Round to the nearest whole number percent if it isn't already.)
You already did the technical stuff. I just added some mechanical things.
The sum of 106 is 100 and 10
The answer is 1800 because you have to follow the formula for volume which is
Volume=Length x Width x Height
1800= 18m x 5m x 20m
A repeating is always a rational number there is no way to convert them just make sure they are repeating in a pattern
1, 4, 13, 40, 121, 364, 1,093, 3,280, 9,841, 29,524, 88,573.
Hoped this helped :)
