draw a line ab 12 cm long. mark on it such that AC is 2 by 3 of AB. Mark D as such that ad is 1 by 4 of AC. What is the fraction of AB is AD?
Answers
Step-by-step explanation:
Draw the line AB, 12cm long
Mark C on it such that AC is 2/3 of AB
Mark D such that AD is 1/4 of AC
To find:
What fraction of AB is AD?
Solution:
We have,
AC = \frac{2}{3} \times AB
3
2
×AB
substituting the value of AB = 12 cm
\implies AC = \frac{2}{3} \times 12⟹AC=
3
2
×12
\implies AC = 2 \times 4⟹AC=2×4
\implies \bold{AC = 8\:cm}⟹AC=8cm
Also,
AD = \frac{1}{4} \times AC
4
1
×AC
substituting the value of AC = 8 cm
\implies AD = \frac{1}{4} \times 8⟹AD=
4
1
×8
\implies AD = 1 \times 2⟹AD=1×2
\implies \bold{AD = 2\:cm}⟹AD=2cm
Therefore, substituting the value of AD = 2 cm & AB = 12 cm, we get
The ratio of AD and AB
i.e., \frac{AD}{AB} = \frac{2}{12}
AB
AD
=
12
2
\implies \frac{AD}{AB} = \frac{1}{6}⟹
AB
AD
=
6
1
\implies \bold{AD = \frac{1}{6} \times AB}⟹AD=
6
1
×AB
Thus, AD is \underline{\bold{\frac{1}{6}^t^h }} of line AB.
