It is the same as 13n-25 simplified
13/25 or 7/8 Same as 104/200 or 175/200 You decide
Multiply the numerator and the denominator by the same number and so 25/13 = 50/26
You are asking for the arithmetic mean for 25 consecutive integers starting at 13. (13+14+...+36+37) / 25 = 25 But there is a trick to this question. Since (13+37)/2 = (14+36)/2 = (15+35)/2 = ... = (24+26)/2 = 25/1 = 25, you only needed to calculate (13+37)/2 =25. The same is true for any sum of consecutive integers. For more information, look up "arithmetic series".
There are 2 cups/pint; so they are both the same.
Convert to same units then the comparison an be made: 1 qt = 2 pt → 13 qt = 13 × 2 pt = 26 pt 25 < 26 → 25 pt < 26 pt → 25pt < 13 qt → 25 pints are less than 13 quarts.
25-13 = 12
13 / 25 = 0.52
-13/25 = -13 ÷ 25 = -0.52
No. Convert to equivalent fractions with the same denominator and then compare numerators: 7/15 = (7×5)/(15×5) = 35/75 13/25 = (13×3)/(25×3) = 39/75 35 < 39 → 35/75 < 39/75 → 7/15 < 13/25.
25 is 192.31% of 13, to two decimal places.
These two odd numbers are 39 and 65. Both are between 25 and 75, and their GCF is 13.
