Time taken by Ella is 0.6 hour

<u>Solution:</u>

Lily finished a task in \frac{3}{4} hour

Ella finished it in \frac{4}{5} of time Lily took

<em><u>To find: time taken by Ella to finish the task</u></em>

Let "L" be the time taken by Lily

Time taken by Lily = L = \frac{3}{4} \text{ hour }

From given statement,

Time taken by Ella to finish the task is \frac{4}{5} of time Lily took

Therefore,

Time taken by Ella = \frac{4}{5} of time taken by Lily

\text{ Time taken by Ella } = \frac{4}{5} \text{ of } \frac{3}{4}\\\\\text{ Time taken by Ella } = \frac{4}{5} \times \frac{3}{4}\\\\\text{ Time taken by Ella } = \frac{3}{5}\\\\\text{ Time taken by Ella } = 0.6

Thus time taken by Ella is 0.6 hour

Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT
