Find two numbers, both smaller than 100, that have common multiple of 450 and highest common factor of 15

hello :

90 = 15×6

75 =  15× 5

highest common factor of 90 and is 15 because highest common factor of 5 and 6 is 1

90 = 3² ×2×5

75= 5^3

common multiple of 90 and 75 is : 3²×2×5²  = 450

90 and 75  both smaller than 100.

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
