Which pair of fractions are proportional? a)36/54 and 6/9 b)6/7and 16/21 c) 21/36and 21/42 d) 14/35 and 21/42

Option A

are proportional.

Solution:

If two fractions are equal, than it is said to be in proportion.

Case 1:  

Consider option A

Given fractions are

Hence both the fractions are equal. So they are propotional.

Case 2:

Consider option 2

Given fractions cannot be simplified further. Also both the fractions are not equal. So they are not propotional.

Case 3:

Consider option 3

Given fractions are

Hence are not equal. Hence they are not propotional.

Case 4:

Consider option 4  

Given fractions are

Hence are not equal. Hence they are not propotional.

The answer for the given question is option A  

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
