Evaluate 1 whole number 2/5 + 3/4 and give your answer to one significant figure

ehidna [41]

Answer:

The answer is

<h3>2 to 1 significant figure</h3>

Step-by-step explanation:

$1 \frac{2}{5} + \frac{3}{4}$

To solve the question first convert the mixed fraction to an improper fraction

That's

$1 \frac{2}{5} = \frac{7}{5}$

So we have

$\frac{7}{5} + \frac{3}{4}$

Find the LCM of the fractions

The LCM of 5 and 4 is 20

That's

$\frac{7}{5} + \frac{3}{4} = \frac{7(4) + 3(5)}{20} = \frac{28 + 15}{20}$

$= \frac{43}{20}$

= 2.15

We have the final answer as

<h3>2 to 1 significant figure</h3>
