Iam a number less than 100. two of my factors are three and five. my digits are one apart. what number am i?

factors 3 & 5

3*5 = 15

15, 30, 45, 60, 75, 90 are all the possible choices

 so the answer would be 45 since the numbers are only 1 apart

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
