To answer this item, we let x be the number of counters that Max has. By the representation, the number of counters that Jack has is 3x.
a. Ratio of counters,
3x:x
which can be simplified by dividing by x both sides of the ratio giving us the answer of,
3:1
b. Fraction of counters Max have,
fraction = x / (x + 3x) = 1/4
Answer:
3
Step-by-step explanation:
It is a well known trick that when you add together the digits of a number, if they are a multiple of 3 then the number is divisible by 3. Let's go through the options and check them:
7+5+7+0=19 not a multiple of 3
7+5+7+1=20 not a multiple of 3
7+5+7+2=21 multiple of 3
7+5+7+3=22 not a multiple of 3
7+5+7+4=23 not a multiple of 3
7+5+7+5=24 multiple of 3
7+5+7+6=25 not a multiple of 3
7+5+7+7=26 not a multiple of 3
7+5+7+8=27 multiple of 3
7+5+7+9=28 not a multiple of 3
As you can see, only 3 of these were possibilities that satisified the conditions. Hope this helps!
Answer:
Below
Step-by-step explanation:
900 + 20 + 5
So, 6 x 900 + 6 x 20 + 6 x 5
6 x 925 = (6 x 900) + (6 x 20) + (6 x 5)
= 5400 + 120 + 30
= 5550
