Answer:

126

Step-by-step explanation:

21 + 4 = 25  (blue plus white marbles)

150/25 = 6 (all the marbles divided by how many we know are white and blue)

21 x 6 = 126

Find the quotient. 22x2y2 ÷ 11x2y2
Sloan [31]

Quotient = 2

Solution:

Given expression is 22x^2y^2\div11x^2y^2.

To find the quotient.

22x^2y^2\div11x^2y^2=\frac{22x^2y^2}{11x^2y^2}

In numerator 22 can be written as 2 × 11.

\frac{22x^2y^2}{11x^2y^2}=\frac{2\times11x^2y^2}{11x^2y^2}

Take common term out in the numerator and denominator.

\frac{22x^2y^2}{11x^2y^2}=\frac{(11x^2y^2)(2)}{11x^2y^2}

Common terms in the numerator and denominator will be cancelled.

\frac{22x^2y^2}{11x^2y^2}=2

Hence the quotient is 2.
