How can you get 3/3 -1/6?
cluponka [151]

9514 1404 393

Answer:

  5/6

Step-by-step explanation:

Addition or subtraction of fractions requires a common denominator. The value 3/3 can be multiplied by 2/2 to give 6/6, which has the same denominator as the other fraction.

  \dfrac{3}{3}-\dfrac{1}{6}=\dfrac{3\cdot2}{3\cdot2}-\dfrac{1}{6}\\\\=\dfrac{6}{6}-\dfrac{1}{6}=\dfrac{6-1}{6}=\boxed{\dfrac{5}{6}}

Suzanna walked two over seven of a mile in two over five of an hour. What is her unit rate in miles per hour?
Kruka [31]

Two sevenths over two fifths = five over seven mile per hour

The unit rate is 5 over 7 miles per hour

<em><u>Solution:</u></em>

Given that, Suzanna walked two over seven of a mile in two over five of an hour

We have to find the unit rate in miles per hour

Unit rate means number of miles covered in 1 hour

From given information,

Two over seven of a mile in two over five of an hour

Which means,

\frac{2}{7} \text{ miles } = \frac{2}{5} \text{ hour }

\text{ So she covered } \frac{2}{7} \text{ miles in } \frac{2}{5} \text{ hour }

To find for number of miles covered in 1 hour, divide the \frac{2}{7} \text{ by } \frac{2}{5}

\text{Unit rate in miles per hour } = \frac{\frac{2}{7}}{\frac{2}{5}}\\\\\text{Unit rate in miles per hour } = \frac{2}{7} \times \frac{5}{2} = \frac{5}{7}

Two sevenths over two fifths = five over seven mile per hour

Thus unit rate is 5 over 7 miles per hour
