Question

Find the product
$1.2\times2\frac{2}{5}\times\frac{3}{4}$

• A. 2.4
• B. 2.5
• C. 2.6
• D. 2.1

Answer 1

Answer:

C. 2.6

Convert the mixed number and decimal to fractions:

• $(1.2 = \frac{12}{10} = \frac{6}{5})$

• $(2\frac{2}{5} = \frac{12}{5})$

Now multiply:

• $\frac{6}{5}\times\frac{12}{5}\times\frac{3}{4}$

Simplify before multiplying:

• $\frac{12}{4}=3$

So,

$\frac{6\times 3\times 3}{5\times 5}$

$\frac{54

Therefore,

$\boxed{\frac{54}{25}}$

or as a mixed number,

$\boxed{2\frac{4}{25}}$

or (2.16) in decimal form
