Simplifying
2x + -3(3 * 0.6x + 2.7)

Multiply 3 * 0.6
2x + -3(1.8x + 2.7)

Reorder the terms:
2x + -3(2.7 + 1.8x)
2x + (2.7 * -3 + 1.8x * -3)
2x + (-8.1 + -5.4x)

Reorder the terms:
-8.1 + 2x + -5.4x

Combine like terms: 2x + -5.4x = -3.4x
-8.1 + -3.4x

John purchased 24 chocolates for 3 96. How many chocolates can be purchased for

alukav5142 [94]

<h2>|| <u>Question</u> ||</h2>

John purchased 24 chocolates for Rs.96. How many chocolates can be purchased for Rs.72?

<h2>|| <u>Answer</u> ||</h2>

John purchased 24 chocolates = Rs.96.

Chocolates can be purchased for Rs.72 = x

<h3> $\frac{24}{96} = \frac{x}{72}$ </h3>

24:96 = x:72

Means = Extreams

96 × x = 24 × 72

<h3> $x = \frac{24 \times 72}{96}$ </h3>

( 12 × 2 = 24, 12 × 8 = 96 )

<h3> $x = \frac{2 \times 72}{8}$ </h3>

(8 × 1 = 8, 8 × 9 = 72)

<h3> $x = \frac{2 \times 9}{1}$ </h3><h3> $x = 2 \times 9$ </h3><h3> $x = 18$ </h3>

Therefore, 18 chocolates can be purchased for Rs.72
