Answer:

Option (D)

Step-by-step explanation:

Given expression is,

x³ × 3 ÷ \frac{2}{9} + 9x - (7 - 6x)

By substituting x = \frac{2}{3},

(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})]

By using rule PEMDAS,

P - Parenthesis

E - Exponent

M - Multiplication

D - Division

A - Addition

S - Subtraction

=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4]

= (\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3

= \frac{8}{27}\times 3 \div \frac{2}{9}+6-3

= \frac{8}{9}\div \frac{2}{9}+6-3

= \frac{8}{9}\times \frac{9}{2}+6-3

= 4 + 6 - 3

= 7

Option (D) is the answer.

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be \frac{27}{2}

\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}
