To obtain the HCF of two positive integers, say c and d, with c > d, follow the steps below: Step 1 : Apply Euclid’s division lemma, to c and d. So, we find whole numbers, q and. r such that c = dq + r, 0 r < d. ≤. Step 2 : If r = 0, d is the HCF of c and d. If r 0, apply the division lemma to d and r. ≠.

9. Four quantities are said to be in proportion, if the ratio of the first and the second quantities is equal to the ratio of the third and the fourth quantities. Thus, 3, 10, 15, 50 are in proportion, since 315 . 10 50 = We indicate the proportion by 3:10 :: 15:50, it is read as 3 is to 10 as 15 is to 50.

Step 1 : First multiply both the equations by some suitable non-zero constants to make the coefficients of one variable (either x or y) numerically equal. Step 2 : Then add or subtract one equation from the other so that one variable gets eliminated. If you get an equation in one variable, go to Step 3.

An algebraic equation is an equality involving variables. It says that the value of the expression on one side of the equality sign is equal to the value of the expression on the other side. The equations we study in Classes VI, VII and VIII are linear equations in one variable. In such equations, the expressions which form the equation contain ...

Theorem 10.1 : The tangent at any point of a circle is perpendicular to the radius through the point of contact. Proof : We are given a circle with centre O and a tangent XY to the circle at a point P. We need to prove that OP is perpendicular to XY. Take a point Q on XY other than P and join OQ (see Fig. 10.5).
