Okay so first I just go to the wording of the first part, reading it again as something like "85 is 34% of what number?" Then I translate it by putting an = for the "is", an x (times) for the "of", and a variable, w for "what number". Because it's a percent, we get rid of the % sign by writing 34/100, or .34 . Then we just have:
85=.34 x a
Divide off the .34
a=250
Now for the second part. 250 is the total number of pages, so subtract 85 to get the number of pages she hasn't read.
250-85=165
So she has more than 125 pages left.

What is the maximum number of children among whom 32 red marbles, 144 blue marbles and 176 green marbles can be divided equally

Leto [7]

Answer:

Maximum number of children among whom 32 red marbles, 144 blue marbles and 176 green marbles can be divided equally is 16.

Step-by-step explanation:

Finding HCF of 32, 144, 176

32 = 2 * 2 * 2 * 2 * 2

144 = 2 * 2 * 3 * 2 * 2 * 3

176 = 2 * 2 * 2 * 11 * 2

HCF = 2 * 2 * 2 * 2 = 16
