Instead of the three dots, write a digit to make the fraction reducible. (Find all possible cases.) 15/2...7

possible digits: 0, 3, 6 or 9

Step-by-step explanation:

To make the fraction reducible, the number in the denominator needs to have a common prime factor with the number in the numerator.

The number in the numerator can be factored in 3 * 5, so the denominator needs to be multiple of 3 or 5.

To be multiple of 5, the last number needs to be 0 or 5, which is not the case.

To be multiple of 3, the sum of the digits needs to be a multiple of 3.

The sum of the digits is 2 + x + 7, with x being the missing digit.

To have a multiple of 3, we have that x + 9 needs to be multiple of 3, so we can have x=0, x=3, x=6 or x=9, which would give us the fractions:

x=0: 15/207 = 5/69

x=3: 15/237 = 5/79

x=6: 15/267 = 5/89

x=9: 15/297 = 5/99

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
