Question

Thrice the sum of three fifths and two thirds less one half is what number?

Answer 1

Answer:

$3 (\frac{3}{5} + \frac{2}{3} ) -\frac{1}{2} = 3 \frac{3}{10}$

Given:

Let the number be $x$

To find:

$3 (\frac{3}{5} + \frac{2}{3} ) -\frac{1}{2}$

Explanation:

$3 (\frac{3}{5} + \frac{2}{3} ) -\frac{1}{2} = x\\\\\3(\frac{9}{15} + \frac{10}{15}) - \frac{1}{2} = x$

$3(\frac{19}{15}) - \frac{1}{2}$ $= x$

$\frac{3}{1}$ × $\frac{19}{15} - \frac{1}{2} = x$

$\frac{57}{15} - \frac{1}{2}$ $= x$

$x = \frac{99}{30}$

$x = \frac{33}{10}$

Answer:

Therefore, thrice the sum of three fifths and two thirds less one half is $3 \frac{3}{10}$
