YES
Base=b
Height= h
Area 1=A1=1/2*b*h
Base=b
Height= 4h
Area of triangle 2=A2=1/2*b*4h
A2/A1= (1/2*b*4h)/(1/2*b*h)
= (1/2*b*4h)/(1/2*b*h)
=4/1
Ratio of heights =h2/h1= 4/1
Ratio of areas =A2/A1= 4/1
They are proportional.
We are multiplying 5/8 by something to get an equivalent fraction. What times 5 equals 10. 2 right? So we multiply the numerator by 2 over 2. This means because we multiplied the numerator by 2 we have to multiply the denominator by 2 as well. 8 x 2=16 so our answer is 10/16 without being simplified. If you need to simplify the answer you would factor out the numbers and divide by 2 over 2 which gets you to 5/8.
