Question

Rita ate ¼ of an apple, her younger brother ate 3/5 part of it

and the remaining part she left for her parents. What fraction

of the apple she left for parents?
​

Answer 1

Answer:

Rita eaten part 1/4

youngervbrithervesten part 3/5

total eaten part 1/4+3/5

=17/20

remaining part

1-17/20

=3/20 for parents

Answer 2

Given:

• Fraction of part Rita ate = $\Large\bold{\frac{1}{4}}$
• Fraction of part her younger brother ate = $\Large\bold{\frac{3}{5}}$
• Rite decided to save the remaining fraction of apple for her parents.

‎

To find:

• The fraction of apple that she left for her parents.

‎

Solution:

To find the fraction of apple that she left for her parents, we should first sum up the fractions which Rita and her brother ate. Then, we should subtract the fractional part from the total fraction of apple. And the difference value equals the share of her parents. So, now let's do it !!

The fraction of apple ate by Rita and her brother:

$\Large\implies{\tt{\frac{1}{4}+ \frac{3}{5}}}$

$\Large\implies\normalsize{\sf{The\:LCM\:of\: denominators\:is\:20.}}$

$\Large\implies{\tt{( \frac{1}{4} \times \frac{5}{5} ) + ( \frac{3}{5} \times \frac{4}{4} )}}$

$\Large\implies{\tt{ \frac{5}{20} \times \frac{12}{20} }}$

$\Large\implies{\tt{ \frac{5 + 12}{20} }}$

$\Large\implies{\tt{\frac{17}{20}}}$

The fraction of apple ate by her parents:

$\Large\implies{\tt{\frac{20}{20}- \frac{17}{20}}}$

$\Large\implies{\tt{\frac{20-17}{20}}}$

$\Large\implies\underline{\boxed{\tt{\red{\frac{3}{20}}}}}$

‎

Final answer:

• Therefore, the fraction of apple ate by her parents is $\Large\bold{\frac{3}{20}}$.
