The quotient of dividing two numbers is 4. Find the new quotient if: a) the dividend was multiplied by 1.5 b) the divisor was multiplied by 8 c) the divisor was divided by 1.6 d) the dividend and the divisor were multiplied by 1.785.

We take the dividend = X, and the divisor = Y, then the quotient = X / Y = 4,

New private:

a) the dividend was multiplied by 1.5:

X * 1.5 / Y = 4 * 1.5 = 3;

b) the divisor is multiplied by 8:

X / (8 * Y) = 4/8 = 0.5;

c) the divisor was divided by 1.6:

X / (Y / 1.6) = 4 * 1.6 = 6.4;

d) the dividend and divisor are multiplied by 1.785:

X * 1.785 / (Y * 1.785) = X / Y = 4.
