Question

Kirmera is given R240, her mother tells her to spend 3/8 on flour, 1 /5 on sugar and to bring home the change. What fraction of the money will she bring

Answer 1

Step-by-step explanation:

total = 240

spend on flour = 3/8 of 240

= 3/8 × 240

= 90

spend on sugar = 1/5 of 240

. = 1/5 × 240

= 48

total spend = 90 + 48 =138

remain = 240 - 138

= 102

fractions = 102/ 240

=51/ 120

= 17/40

Answer 2

Given:

Kirmera is given Rs. 240,

Her mother tells her to spend $\frac{3}{8}$ on flour,

And $\frac{1}{5}$ on sugar and to bring home the change.

Now,

To be found:

What fraction of the money will Kirmera bring?

Let that fraction be x

Now,

All fraction's sum will be one whole

So,

$\rm x + \frac{3}{8} + \frac{1}{5} = 1 \\ \\ \implies \rm x+ \frac{15+8}{40} = 1 \\ \\ \implies \rm x+ \frac{23}{40} = 1 \\ \\ \implies \rm x = 1 - \frac{23}{40} \\ \\ \implies \rm x = \frac{40-23}{40} \\ \\ \implies \rm x = \frac{17}{40}$

So,

She will bring $\frac{17}{40}$ a fraction of money with her in return.
