Question

an apple is cut into 10 pieces. 0.8 of the apple is eaten. which fraction ,in simplest form ,represents the amount of the apple left?

Answer 1

Answer:

The apple left is $\frac{1}{5}$

Step-by-step explanation:

The apple is cut into 10 pieces and 0.8 of it is eaten. To show it in fractions we have:

Complete fruit: $\frac{10}{10}$

Eaten part: $0.8=\frac{8}{10}$

To represent the amount of apple left we have to subtract both values:

$\frac{10}{10} - \frac{8}{10} = \frac{2}{10} = Apple left$

Finally, the$\frac{2}{10}$ fraction could be reduced because both of the values of the fraction could be divided by 2, this is:

$\frac{2/2}{10/2} =\frac{1}{5}$

Answer 2

The apple is cut into 10 pieces so each piece is 1/10 of the apple. 1/10=.1; .8=8/10 so 8 pieces are eaten. 2 pieces are left which is 2/10 of the apple which simplifies to 1/5 because 2 and 10 are both divisible by 2. 2 divided by itself is 1 and 10 divided by 2 is 5. So the amount of the apple left in simplest form of a fraction is 1/5.
