1 4/6 make the 6 a 12 and the four a 8. 1= 12/12 so 8+12=20 so 20/12 and 20 is 10/12 more that 10/12 or twice as much.

Explanation & Answer:

You want to make sure both fractions have the same denominator.

10/12 and 1 4/6

We will convert the second fraction.

It is a mixed fraction, so we will make it an improper fraction.

\frac{(1*6)+4}{6} = \frac{10}{6}

Now we need to make it have the same denominator by multiplying.

2/2 * 10/6 = 20/12

The 10 day old worm is 10/12 inches long.

The 20 day old worm is 20/12 inches long.

This means the 20 day old worm is 10/12 inches longer. We can simplify this by dividing both the numerator and denominator by the same number - 2.

10/12 = 5/6

The 20 day old worm is 5/6 inches longer.
