Question

a varies as b . When a =20 and b = 0.35, what is the constant of proportionality?​

Answer 1

★Given:-

• a = 20
• b = 0.35

★To find:-

• Constant of proportionality

★Solution:-

• Let the constant of proportionality be k.

Then According to question,

$\pink{A = \frac{K}{B}} \\ \\ \purple{20 = \frac{K}{0.35}} \\ \\ \color{purple} K = \frac{35 \times 20}{100} \\ \\ \green{= 7}$

Hence, The Answer is 7.

Answer 2

Answer:

❣Answer❣

◑ $a = \frac{k}{b}$

◑ $20 = \frac{k}{0.35}$

◑ $k = \frac{35 \times 20}{100}$

◑ $= 7$
