Keep note of these things before we start:
-Of is a keyword that tells us multiplication is being done
-x = total number of pages
-32% = 32/100 = .32
Okay, here we go:
32% of total number of pages = 80
.32 of x = 80
.32*x = 80
.32x = 80
.32x/.32 = 80/.32
x = 250
There are 250 pages in total in Katie's book.
To find out how many pages she has to read (y), subtract the pages read from the total:
TOTAL - PAGES READ = PAGES LEFT TO READ
250 - 80 = y
170 = y
Katie has 170 pages left to read
Hope this helps!
77 feet I according to my calculations :)
The square root of 25/64=5/8
So you can say that the weight of a koala here can be x.
So x * 1/8 = 2
2 being the chinchilla's weight and the 1/8 coming from the fact that the chinchilla weighs 1/8 of the weight of the koala.
So you can just divide both sides by 1/8 first.
x * 1/8 = 2
/ 1/8 / 1/8
Or,
x *1/8 * 8/1 = 2 * 8/1
x = 16
So the koala weighs 16 pounds.
In this equation x equals the number that came previously in the sequence.
The equation you need is ½x. That is the term to term for this question.
