After completing the fraction division 5 divided by five-thirds, Miko used the multiplication shown to check her work.

3 times five-thirds = StartFraction 3 Over 1 EndFraction times five-thirds = StartFraction 15 Over 3 EndFraction or 5

Which is the most accurate description of Miko’s work?
Miko found the correct quotient and checked her work using multiplication correctly.
Miko found the correct quotient but checked her work using multiplication incorrectly.
Miko found an incorrect quotient but checked her work using multiplication correctly.
Miko found an incorrect quotient and checked her work using multiplication incorrectly.

1 answer

To evaluate Miko’s work, we first need to confirm the division of \( 5 \) by \( \frac{5}{3} \).

The division \( 5 \div \frac{5}{3} \) can be rewritten as:

\[ 5 \cdot \frac{3}{5} \]

This simplifies to:

\[ \frac{5 \cdot 3}{5} = \frac{15}{5} = 3 \]

So, the correct quotient is \( 3 \).

Next, we look at Miko’s multiplication check:

Miko multiplied \( 3 \) by \( \frac{5}{3} \):

\[ 3 \cdot \frac{5}{3} = \frac{3 \cdot 5}{3} = \frac{15}{3} = 5 \]

This means she got \( 5 \), which is the original number she started with.

Thus, in conclusion:

  • Miko found the correct quotient of \( 3 \).
  • She checked her work by multiplying back and, indeed, got back to \( 5 \).

So, the most accurate description of Miko’s work is:

Miko found the correct quotient and checked her work using multiplication correctly.
